EEBCLK — EEPROM Bus Clock Enable
This read/write bit determines which clock will be used to drive the
internal charge pump for programming/erasing. Reset clears this bit.
1 = Bus clock drives charge pump
0 = Internal RC oscillator drives charge pump
NOTE:
It is recommended that the internal RC oscillator is used to drive the
internal charge pump for applications that have a bus frequency of less
than 8 MHz.
EEOFF — EEPROM Power Down
This read/write bit disables the EEPROM module for lower power
consumption. Any attempts to access the array will give unpredictable
results. Reset clears this bit.
1 = Disable EEPROM array
0 = Enable EEPROM array
NOTE: The EEPROM requires a recovery time, t_EEOFF, to stabilize after clearing
the EEOFF bit.
