C.13 EEPROM Control/DO State Register
Base+0x3C: EEPROM DO state Register
Bit 0: EEPROM DO state
Through this register you can set the power up status and watchdog timer
overflow states in the EEPROM.
• CS: EEPROM select
• CLK: EEPROM clock
• DI: EEPROM data in
• DO: EEPROM data out
The data format of EEPROM:
Base+0x3C (Read)
Bit 15 - Bit 1 Bit0
N/A DO
Base+0x3C (Write)
Bit 15 - Bit 4 Bit3 Bit2 Bit1 Bit0

instead of through this register directly.
