Note:
EEPROM Data Memory
The 128 8 bits EEPROM data memory is readable and writable during normal operation. It is indirectly addressed
through the control register EECR ([40H] in Bank 1). The EECR can be read and written to only by indirect addressing
mode using MP1.

*1: To make sure that the system oscillator has stabilized, the SST provides an extra delay of 1024 system
*2: Since low voltage state has to be maintained its original state for longer than 1ms, therefore after 1ms delay,
clock pulses before starting the normal operation.
