Note:
WDTMR During STOP (D3)
This bit determines whether or not the WDT is active during STOP Mode. Because 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.
EPROM Selectable Options
There are seven EPROM Selectable Options to choose from based on ROM code require-
ments. These options are listed in
Table 16. EPROM Selectable Options
Voltage Brown-Out/Standby
An on-chip Voltage Comparator checks that the V

Low-Voltage Detection Register—LVD(D)0Ch
Voltage detection does not work at STOP mode. It must be disabled during STOP mode in
order to reduce current.
