Symbol
Function
COEN
Clock Divider Enable
0: Disable Clock Divider
1: Enable Clock Divider
CO_SEL
Clock Divider Selection
00b: 1/4 clock source
01b: 1/16 clock source
10b: 1/256 clock source
11b: 1/1024 clock source
CO_IN
Clock Source Selection
0b: Select clock from 1x clock
1b: Select clock from 2x clock
The default value of this bit is set during Power-on reset by copying from
Enable_Clock_Double_i non-volatile bit setting. CO_IN can be changed during normal
operation to select the double clock option.
If the clock source is a 1x clock, the clock divider exports 1/4, 1/16, 1/256, or 1/1024 of
the input clock.
If the clock source is a 2x clock, the clock divider exports 1/2, 1/8, 1/128, or 1/512 of the
input clock.

WDU
Watchdog Timer Clock Control
0:The clock for the Watchdog timer is running
1:The clock for the Watchdog timer is stopped
TCT
Timer 0/1 Clock Control
0:The Timer 0/1 logic is running
1:The Timer 0/1 logic is stopped
TCT2
Timer 2 Clock Control
0:The Timer 2 logic is running
1:The Timer 2 logic is stopped
PB2
Further Power Control 2
0:The PB2 logic is running
1:The PB2 logic is stopped
PB1
Further Power Control 1
0:The PB1 logic is running
1:The PB1 logic is stopped
Power consumption can be decreased by setting both PB2 and PB1 to 1.
