Enable Status_EEPROM
on STATUS0 pin
Enables the EEPROM status on the STATUS0 pin.
1: enable status.

STATUS1 pin divider
enable
Enables a divide-by-4 on the STATUS1 pin, allowing dynamic signals to be viewed at a lower
frequency (such as the PFD input clocks). Not to be used with dc states on the status pins,
which occur when the settings of Register 0x231, Bits[5:0] are in the range of 000000 to 001111.
1: enabled.
0: disabled.
