Bits 2..0 - WDPS2..0: WatchDog Prescaler Select Bits 2 - 0
The WDPS2, WDPS1, and WDPS0 bits determine the Watchdog Timer prescaling clock output
(CLK
WD) when the Watchdog Timer is enabled. The different prescaling values and their corre-
sponding Timeout periods are shown in Table 3-31.

Timer0 Control Register – T0CR
Bits 7 to 5 – T0PBS2..0: Timer0 Prescaler B Select Bits 2 to 0
The T0PBS2, T0PBS1, and T0PBS0 bits determine the Timer0 prescaling clock output
(CLK
SEN) and additionally the mode of the motion sensor. The different prescaling values and
their corresponding time-out periods are shown in Table 3-32.
