Watchdog
The watchdog is activated on the first write to its control register SFR 0xAD. It can not
be disabled by any other means than a reset. The watchdog register is loaded by writing
a 16-bit value to the two 8-bit data registers (SFR 0xAB and 0xAC) and then the writing
the correct opcode to the control register. The watchdog will then count down towards 0
and when 0 is reached the complete microcontroller will be reset To avoid the reset, the
software must load new values into the watchdog register sufficiently often.
16.6
Programming Interface to Watchdog and Wakeup Functions
Figure 16 shows how the blocks that are always active are connected to the CPU. RTC
timer GPIO wakeup and Watchdog are controlled via SFRs 0xAB, 0xAC and 0xAD.
These 3 registers REGX_MSB, REGX_LSB and REGX_CTRL are used to interface the
blocks running on the slow CKLF clock. The 16-bit register {REGX_MSB,
REGX_LSB} can be written or read as two bytes from the CPU.
