To reset Watchdog Timer, write any value beteen 00h and 7Eh to this register.
This value is loaded to the 7 most significant bits of the 22-bit counter.
For example: MOV WDRST,#1EH
Reset period
(1.258 second at 40Mhz)
(about 6.291 seconds at 8Mhz)
Reset pulse width (about 10ms at 40Mhz, about 50ms at 8Mhz)
