Bit 3~2

BZEN1,BZEN0: BZ/BZ enable/disable

00: both disabled

01: reserved

10: BZ only enabled

11: BZ and BZ enabled

When BZ or BZ is disabled, the I/O port will have general I/O functions. If enabled, the BZ or BZ

outputs will still be controlled by the related I/O port control and data settings. Refer to the Buzzer

function section for details.

Bit 1

LXTLP: LXT oscillator low power control function

0: LXT oscillator quick start-up mode

1: LXT oscillator low power mode

Bit 0

CLKMOD: system clock mode selection.

0: high speed - HIRC used as system clock

1: low speed - LXT used as system clock, HIRC oscillator stopped.

These selections are only valid if the oscillator configuration options

have selected the HIRC+LXT.

WDTEN3, WDTEN2, WDTEN1, WDTEN0: WDT function enable

1010: WDT disabled

Other values: WDT enabled - Recommended value is 0101

If the

²watchdog timer enable² configuration option is selected, then the watchdog timer will

always be enabled and the WDTEN3~WDTEN0 control bits will have no effect.

Note:

The WDT is only disabled when both the WDT configuration option is disabled and when bits

WDTEN3~WDTEN0=1010.

The WDT is enabled when either the WDT configuration option is enabled or when bits

WDTEN3~WDTEN0

¹1010.
