28.2.1
Register 28-16 shows the WDTCON register. This is a
readable and writable register which contains a control
bit that allows software to override the WDT Enable
Configuration bit, but only if the Configuration bit has
disabled the WDT.

2:
This bit has no effect if the Configuration bits, WDTEN<1:0>, are enabled.
This bit is available only when ENVREG = 1 and RETEN = 0 .
CONTROL REGISTER
REGSLP: Regulator Voltage Sleep Enable bit
1 = Regulator goes into Low-Power mode when device’s Sleep mode is enabled
0 = Regulator stays in normal mode when device’s Sleep mode is activated
Unimplemented : Read as ‘ 0 ’
ULPLVL: Ultra Low-Power Wake-up Output bit
Not valid unless ULPEN = 1 .
1 = Voltage on RA0 pin > ~ 0.5V
0 = Voltage on RA0 pin < ~ 0.5V.
SRETEN: Regulator Voltage Sleep Disable bit
1 = If RETEN (CONFIG1L<0>) = 0 and the regulator is enabled, the device goes into Ultra Low-Power
0 = The regulator is on when device’s Sleep mode is enabled and the Low-Power mode is controlled
Unimplemented : Read as ‘ 0 ’
ULPEN: Ultra Low-Power Wake-up Module Enable bit
1 = Ultra low-power wake-up module is enabled; ULPLVL bit indicates the comparator output
0 = Ultra low-power wake-up module is disabled
ULPSINK: Ultra Low-Power Wake-up Current Sink Enable bit
Not valid unless ULPEN = 1 .
1 = Ultra low-power wake-up current sink is enabled
0 = Ultra low-power wake-up current sink is disabled
SWDTEN: Software Controlled Watchdog Timer Enable bit
1 = Watchdog Timer is on
0 = Watchdog Timer is off
