Example for RC type AD converter mode (Timer B overflow):
clr tmrc
clr adcr.1
; set timer mode
clr intc1.4
; clear timer/event counter interrupt request flag
mov a, 00h
; give timer A initial value
mov tmrbl, a
mov a, 00h
mov tmrbh, a
mov a, 00010011b
; RS0~CS0; set RC type ADC mode; set Timer B overflow
mov adcr,a
mov a, low (65536-1000)
; give timer B initial value
mov tmrbl, a
; count 1000 time and then overflow
mov a, high (65536-1000)
mov tmrbh, a
mov a, 00110000b
; timer A clock source=T1 and timer on
mov tmrc, a
p10:
clr wdt
snz intcl.4
; polling timer/event counter interrupt request flag
jmp p10
clr intcl.4
; clear timer/event counter interrupt request flag
; program continue
