CSEL — Clock Select Bit
To write to any EEPROM byte, it must first be erased, for instance, all of
its bits must be set. A single byte, a row, or the entire EEPROM in a
single procedure can be erased by adjusting the BYTE and ROW bits in
PPROG. Once the targeted area has been erased, each byte can be
individually written.

Selects the built-in RC clock source for on-chip EEPROM and A/D
charge pumps. This clock should be used when the E clock falls
below 1 MHz.
