NOTE:
Address:
This read/write register controls programming/erasing of the array.
EEBCLK — EEPROM Bus Clock Enable
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
The EEPROM requires a recovery time, t
the EEOFF bit.

This read/write bit determines which clock will be used to drive the
internal charge pump for programming/erasing. Reset clears this bit.
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.
