CSEL — Clock select
Selects alternate clock source for on-chip EPROM , EEPROM and A/D charge pumps. The on-chip
RC clock should be used when the E clock frequency falls below 1MHz.
IRQE — Configure IRQ for falling edge sensitive operation (refer to Section 3)
DLY — Enable oscillator start-up delay (refer to Section 3)
CME — Clock monitor enable (refer to Section 10)
FCME — Force clock monitor enable (refer to Section 10)
CR[1:0] — COP timer rate select bits (refer to Section 10)

A/D, EPROM and EEPROM use internal RC clock source
(about 1.5MHz).
A/D, EPROM and EEPROM use system E clock
(must be at least 1MHz).
Falling edge sensitive operation.
Low level sensitive operation.
A stabilization delay is imposed as the MCU is started up from STOP
mode or from power-on reset.
The oscillator start-up delay coming out of STOP is bypassed and the
MCU resumes processing within about four bus cycles. A stable
external oscillator is required if this option is selected.
Clock monitor enabled.
Clock monitor disabled.
Clock monitor enabled, cannot be disabled until next reset.
Clock monitor follows the state of the CME bit.
