ADPU — A/D Converter Power-Up
0 = A/D converter disabled and powered down
1 = A/D converter is enabled and powered on
CSEL — Clock Select
0 = A/D and EEPROM use the system E clock
1 = A/D and EEPROM use internal RC clock
IRQE — IRQ Select Edge-Sensitive Only
Refer to 5 Resets and Interrupts.
DLY — Enable Oscillator Start-up Delay
0 = No stabilization delay on exit from STOP mode.
1 = A delay of approximately 4000 E-clock cycles is imposed as the MCU exits STOP mode.
CME — Clock Monitor Enable
Refer to 5 Resets and Interrupts.
Bit 2 — Not implemented
Always reads zero
CR[1:0] — COP Timer Rate Select
Refer to 5 Resets and Interrupts.
