Clock Divider Loaded
0 Register has not been written.
1 Register has been written to since the last reset.
0 The oscillator clock is directly fed into the ECLKDIV divider.
1 Enables a Prescalar by 8, to divide the oscillator clock before feeding into the clock divider.
Clock Divider Bits — The combination of PRDIV8 and EDIV[5:0] effectively divides the EEPROM module input
oscillator clock down to a frequency of 150 kHz – 200 kHz. The maximum divide ratio is 512. Please refer to
