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
requirements. These options are listed in
Table 16. EPROM Selectable Options
Voltage Brownout/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.
