SWDT
Watchdog timer start/refresh flag. Set to activate/refresh the watchdog timer.
When directly set after setting WDT, a watchdog timer refresh is performed. Bit
SWDT is reset by the hardware 12 clock cycles after it has been set.
IEN1.5
EX6
EX6 = 0 – disable external interrupt 6.
IEN1.4
EX5
EX5 = 0 – disable external interrupt 5.
IEN1.3
EX4
EX4 = 0 – disable external interrupt 4.
IEN1.2
EX3
EX3 = 0 – disable external interrupt 3.
IEN1.1

EX2 = 0 – disable external interrupt 2.

IP0.6
WDTS
Watchdog timer status flag. Set when the watchdog timer has expired. The
internal reset will be generated, but this bit will not be cleared by the reset.
This allows the user program to determine if the watchdog timer caused the
reset to occur and respond accordingly. Can be read and cleared by software.
Note: The remaining bits in the IP0 register are not used for watchdog control.

Prescaler select bit. When set, the watchdog is clocked through an
additional divide-by-16 prescaler.
WDTREL.6
to
WDTREL.0
WDREL6-0
Seven bit reload value for the high-byte of the watchdog timer. This value is
loaded to the WDT when a refresh is triggered by a consecutive setting of
bits WDT and SWDT.
