After reset, the first two bytes of EEPROM are checked. If the value is 067Bh, the EEPROM is valid and the contents of the EEPROM are loaded as the chip’s default parameters. Otherwise, the chip’s default setting is used. The content of EEPROM is shown in Table 4 below. The Device Configuration Register is used to control some vendor-specific functions. The meaning of each bit in Device Configuration Register is shown in Table 5. Reserved and unused pins always set to the default value. Table 4. EEPROM Content Bytes Name Description 1:0 EECHK When the EEPROM is programmed, these two bytes is configured as 067B. After reset, they will be checked for the value. If matched, the following information will be loaded as the default parameters. 3:2 VID USB Vendor ID 5:4 PID Product ID 7:6 RN Release number (BCD) 10:8 DCR Device Configuration Register Release Date: July, 2002 ds_pl2303_v14 PL-2303 Product Datasheet - 8 - Document Revision 1.3 Table 5.
