The S42WD42/S42WD61 has a watchdog timer with a
nominal timeout period of 1.6 seconds. Whenever the
watchdog times out it will generate a reset output on both
RESET# and RESET. The watchdog timer will reset to t0
whenever the S42WD42/S42WD61 issues an ACKnowledge.
Therefore, the host system will need to issue a start
condition, followed by a valid address and command. It
can be a normal command as in the sequence of reading
or writing to the memory, or it can be a dummy command
issued solely for the purpose of resetting the watchdog
timer...
