stops running and it’s value is kept in the counter. Upon
leaving sleep mode, this timer continues from the value it
had before entering sleep mode.
NOTE:
The duration of the watchdog timeout interval is programmable through the WDT[3:0] bits (See also Table 13: SPI
CONTROL REGISTERS (ALL SPI control registers have Read/Write Access and default to “0” after power−on or hard reset).
The timing is given in Table 12 below.
