主题描述使用程序类型
AM代码的模块当使用程序类型的AM代码之一的内存区域启用块传输时，Rx7i CPU有时会生成块传输（BLT&MBLT）周期以访问相关的存储器。因此，如果内存区域配置为使用程序类型AM代码（AM代码3Ah、3Eh、0Ah或0Eh）之一，请确保至少遵循以下两条规则之一：a）内存区域的接口类型参数不得设置为“Qword Access（64位）”，块传输参数必须设置为“Disabled”-ORb）系统可能不包含具有重叠地址的任何“程序”和“数据”内存区域。（如果不止一个模块响应BLT或MBLT循环，可能会导致系统错误。）通过存储初始值设置强制开启/关闭一旦将强制开启或强制关闭存储到RX7i，用户无法通过下载初始值直接从强制开启切换到强制关闭，反之亦然。用户可以通过下载来关闭力，然后通过另一次下载来打开或关闭力。CMM COMMREQ限制由于CMM固件中的问题，在CMM模块上执行的SNP COMMREQRead System Memory（7202）在长度大于760字的情况下不能正确执行。将错误数据写入SNP主机。用户不应使用超过760个单词的长度。返回为零的活动程序数SNP请求返回控制器类型和ID当前返回的活动程序数目为零。重中断负载下115K下的串行I/O故障在RX7i上重中断负载时115K下运行时，在串行通信中很少出现数据损坏错误。在重载应用中，用户应将串行通信限制在57K或更低。同步备份单元可在恒定扫描模式下记录过扫描故障同步备份单元可以在恒定扫描方式下报告过扫描故障，而不管在扫描中维护IO、逻辑和通信所花费的时间。总线读或写可能返回状态5而不是4。
硬件配置
当结束地址超出范围时，返回的总线读/写状态字可能是4而不是5。硬件配置和初始值可能无法从闪存加载如果在执行写入闪存时CPU RAM中不存在用户逻辑，则CPU可能无法在断电循环后从闪存正确加载。为了保证从闪存正确通电，请确保在写入闪存之前，硬件配置和逻辑都已存储到RAM中。超温运行期间CPU扫描时间增加当CPU的工作温度超过正常工作温度时，系统变量#OVR_TMP（%SA8）打开（故障组24，错误代码0x0001）。当这种情况发生时，扫描时间周期性地增加，因为CPU执行新任务以读取温度传感器报告的实际温度。此增加可能高达2毫秒。扩展机架中的GBC可能无法通电。有时，当关闭/打开扩展机架的电源时，位于该机架中的90-70系列GBC模块可能无法通电源。模块的OK（正常）指示灯将闪烁，然后所有模块指示灯将熄灭。再次关闭机架电源以恢复。（注意：此问题不影响90-30 GBC。）机器版软件可能无法连接。通过以太网将编程器连接到RX7i的尝试将不成功。将不显示正常连接重试对话框。重新启动正在运行程序员的计算机将解决此问题。
Topic Description User Type
Module of AM code When block transfer is enabled using one of the memory areas of the AM code of the program type, the Rx7i CPU sometimes generates a block transfer (BLT&MBLT) cycle to access the relevant memory. Therefore, if the memory area is configured to use one of the program type AM codes (AM codes 3Ah, 3Eh, 0Ah or 0Eh), please ensure that at least one of the following two rules is followed: a) The interface type parameter of the memory area must not be set to "Qword Access (64 bit)", and the block transfer parameter must be set to "Disabled" - ORb) The system may not contain any "program" and "data" memory areas with overlapping addresses. (If more than one module responds to a BLT or MBLT cycle, it may cause a system error.) Forced on/off by storing the initial value setting Once the forced on or forced off is stored in the RX7i, the user cannot directly switch from forced on to forced off by downloading the initial value, and vice versa. The user can close the force by downloading, and then open or close the force by downloading again. CMM COMMREQ Limitation Due to the problem in the CMM firmware, the SNP COMMREQRead System Memory (7202) executed on the CMM module cannot be executed correctly when the length is greater than 760 words. Write the error data to the SNP host. Users should not use a length of more than 760 words. The number of active programs returned as zero The number of active programs returned by the SNP request to return the controller type and ID is currently zero. Serial I/O fault at 115K under heavy interrupt load When running at 115K under heavy interrupt load on RX7i, data corruption errors rarely occur in serial communication. In heavy load applications, the user should limit serial communication to 57K or less. The synchronous backup unit can record the over scan fault in the constant scan mode. The synchronous backup unit can report the over scan fault in the constant scan mode, regardless of the time spent in maintaining IO, logic and communication in the scan. A bus read or write may return status 5 instead of 4.
Hardware configuration
When the end address is out of range, the bus read/write status word returned may be 4 instead of 5. Hardware configuration and initial values may not load from flash memory If there is no user logic in the CPU RAM when writing to flash memory, the CPU may not load correctly from flash memory after a power down cycle. To ensure correct power up from the flash memory, ensure that the hardware configuration and logic are stored in RAM before writing to the flash memory. The CPU scanning time increases during overtemperature operation. When the operating temperature of the CPU exceeds the normal operating temperature, the system variable # OVR_ TMP (% SA8) is open (fault group 24, error code 0x0001). When this happens, the scan time increases periodically because the CPU performs a new task to read the actual temperature reported by the temperature sensor. This increase may be as high as 2 milliseconds. GBCs in expansion racks may not power up. Sometimes, when you turn off/on the power of an expansion rack, the 90-70 series GBC modules located in that rack may not power up. The module's OK LED will flash and all module LEDs will turn off. Turn off the rack power again to recover. (Note: This problem does not affect 90-30 GBC.) The machine version software may not be connected. Attempts to connect the programmer to the RX7i over Ethernet will not succeed. The normal connection retry dialog box will not be displayed. Restarting the computer where the programmer is running will fix this problem.
