both EELAT and EPGM during the same write operation results in
neither bit being set.
This section describes the EEPROM registers:
The EEPROM programming control register (PPROG) controls
programming and erasing. The block protect register (BPROT) can
prevent inadvertent writes to (or erases of) blocks of EEPROM and the
CONFIG register. The CSEL bit in the system configuration options
register (OPTION) selects an on-chip oscillator clock for programming
and erasing when operating at frequencies below 1 MHz.
ODD — Program Odd Rows in Half of EEPROM Bit
EVEN — Program Even Rows in Half of EEPROM Bit
