REGISTER 24-14: WDTCON: WATCHDOG TIMER CONTROL REGISTER
TABLE 24-2:
DS39689F-page 270
RCON
WDTCON
Legend: — = unimplemented, read as ‘0’. Shaded cells are not used by the Watchdog Timer.
Note 1:
Name
The SBOREN bit is only available when the BOREN<1:0> Configuration bits = 01; otherwise, it is disabled
and reads as ‘0’. See Section 5.4 “Brown-out Reset (BOR)”.

SUMMARY OF WATCHDOG TIMER REGISTERS
bit 7
Unimplemented: Read as ‘0’
SWDTEN: Software Controlled Watchdog Timer Enable bit
1 = Watchdog Timer is on
0 = Watchdog Timer is off
Legend:
R = Readable bit
U = Unimplemented bit, read as ‘0’
SBOREN
Note 1: This bit has no effect if the Configuration bit, WDTEN, is enabled.
