latch data for programming the array. Only data with valid
EEPROM address will be latched. If another consecutive valid
EEPROM write occurs, this address and data will override the
previous address and data. Any attempts to read other
EEPROM data will read the latched data. If EELAT is set,
other writes to the EECR1 will only be allowed after a valid
EEPROM write.
cannot be set if the EELAT bit is cleared and a non-EEPROM
write has occurred. When EEPGM is set, the onboard charge
pump generates the program voltage and applies it to the user
EEPROM array. When the EEPGM bit is cleared, the program
voltage is removed from the array and the internal charge
pump is turned off.
single instruction will only clear EEPGM. This is to allow time
for removal of high voltage from the EEPROM array.
