ADPU — A/D Converter Power up
Refer to 9 Analog-to-Digital Converter
CSEL — Clock Select
Refer to 4.10 EEPROM.
IRQE — IRQ Select Edge-Sensitive Only
0 = IRQ input is active-low
1 = IRQ input recognizes falling edges only
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
0 = Clock monitor disabled; slow clock can be used.
1 = Slow or stopped clocks cause COP failure reset.
Bit 2 — Not implemented
Always reads zero
CR[1:0] — COP Timer Rate Select
Refer to the following table of COP timer rates.
