WDT Time Select (D0, D1)
This bit selects the WDT time period. It is configured as shown in
Table 29. WDT Time Select
WDTMR During HALT (D2)
This bit determines whether or not the WDT is active during HALT Mode. A 1 indi-
cates active during HALT. The default is 1.
WDTMR During STOP (D3)
This bit determines whether or not the WDT is active during STOP Mode. Since
the XTAL clock is stopped during STOP Mode, the on-board RC has to be
selected as the clock source to the WDT/POR counter. A 1 indicates active during
STOP. The default is 1.
Clock Source for WDT (D4)
This bit determines which oscillator source is used to clock the internal POR and
WDT counter chain. If the bit is a 1, the internal RC oscillator is bypassed, and the
POR and WDT clock source is driven from the external pin, XTAL1. The default
configuration of this bit is 0, which selects the RC oscillator. See
Notes:
TpC = XTAL clock cycle
The default on reset is 10 ms.
