FOXBORO FBM201d P0922YK输入接口模块
计时器1和2电流计数寄存器（TMRCCR12）计时器1和计时器2的当前计数可通过计时器1和定时器2电流计数计数器（TMRCCR 12）读取，该寄存器位于BAR2中地址的偏移0x20处。该寄存器中的位映射如下：当读取任一字段时，当前计数值被锁存并返回。根据WDT控制状态寄存器（CSR2）中“读取锁存选择”位的设置，有两种模式决定如何锁存计数。有关这两种模式的更多信息，请参阅CSR2寄存器说明。定时器3电流计数寄存器（TMRCCR3）定时器3的电流计数可通过定时器3电流计数器寄存器（TMRC-CR3）读取，该寄存器位于BAR2中地址的偏移0x24处。此寄存器中的位映射如下：读取此字段时，锁存并返回当前计数值。根据WDT控制状态寄存器（CSR2）中“读取锁存选择”位的设置，有两种模式决定如何锁存计数。有关这两种模式的更多信息，请参阅CSR2寄存器说明。
Timer 1 & 2 Current Count Register (TMRCCR12)
The current count of timers 1 & 2 may be read via the Timer 1 & 2 Current Count
Register (TMRCCR12), located at offset 0x20 from the address in BAR2. The mapping
of bits in this register are as follows:
When either field is read, the current count value is latched and returned. There are
two modes that determine how the count is latched depending on the setting of the
“Read Latch Select” bit in the WDT Control Status Register (CSR2). See the CSR2
register description for more information on these two modes.
Timer 3 Current Count Register (TMRCCR3)
The current count of Timer 3 may be read via the Timer 3 Current Count Register
(TMRCCR3), located at offset 0x24 from the address in BAR2. The mapping of bits in
this register are as follows:When this field is read, the current count value is latched and returned. There are
two modes that determine how the count is latched depending on the setting of the
“Read Latch Select” bit in the WDT Control Status Register (CSR2). See the CSR2
register description for more information on these two modes.
