INIT_WATCHDOG:
MOV CCAPM4, #4CH ; Module 4 in compare mode
MOV CCAP4L, #0FFH ; Write to low byte first
MOV CCAP4H, #0FFH ; Before PCA timer counts up to
; FFFF Hex, these compare values
; must be changed
ORL CMOD, #40H ; Set the WDTE bit to enable the
; watchdog timer without changing
; the other bits in CMOD
;
;********************************************************************

WATCHDOG:
CLR EA ; Hold off interrupts
MOV CCAP4L, #00 ; Next compare value is within
MOV CCAP4H, CH ; 255 counts of the current PCA
SETB EA ; timer value
