MC68HC908AS60 — Rev. 1.0
In general, all bits should be erased before being programmed.
However, if program/erase cycling is of concern, minimize bit cycling in
each EEPROM byte. If any bit in a byte requires change from a 0 to a 1,
the byte needs be erased before programming.

non-EEPROM write has occurred. This is to ensure proper
erasing sequence. Once EEPGM is set, the type of erase mode
cannot be modified. If EEPGM is set, the onboard charge pump
generates the erase voltage and applies it to the user EEPROM
array. When the EEPGM bit is cleared, the erase voltage is
removed from the array and the internal charge pump is turned
off.
instruction will only clear EEPGM. This is to allow time for removal
of high voltage from the EEPROM array.
