Description
Write 16 bit data {D1,D0} to Shadow SRAM at
address {A1,A0}
Load Shadow SRAM data to {D1,D0}
Enable MCU reset
Disable MCU reset
Load low byte of MCU stack pointer to D0
Load MCU status register to D0
Load MCU general purpose register to D0
Load MCU RAM to D0
Set break point A[1:0] to {D1,D0}
Erase break point A[1:0]
Continue after break point and disable stepping
Enable stepping
Load high byte of MCU stack pointer to D1
Load program counter value to {A1,A0}
Check data in {D1, D0} against contents of
EEPROM

After power-on reset the IC probes for an EEPROM by sending a device address word and
evaluating its acknowledge status.
If an EEPROM is detected, its contents will be copied to Shadow SRAM and the MCU's reset
signal will be released.
