HT46R016/HT46R017

Enhanced A/D 8-Bit OTP MCU

Timer Program Example

The program shows how the Timer/Event Counter registers are setup along with how the interrupts

are enabled and managed. Note how the Timer/Event Counter is turned on, by setting bit 4 of the

Timer Control Register. The Timer/Event Counter can be turned off in a similar way by clearing the

same bit. This example program sets the Timer/Event Counters to be in the timer mode, which uses

the internal system clock as their clock source.

Timer Programming Example

org 04h

; external interrupt vector

org 08h

; Timer Counter 0 interrupt vector

jmp tmr0int

; jump here when Timer 0 overflows

org 20h

; main program

; internal Timer 0 interrupt routine

tmr0int:

; Timer 0 main program placed here

begin:

; setup Timer 0 registers

mov a,09bh

; setup Timer 0 preload value

mov tmr0,a

mov a,081h

; setup Timer 0 control register

mov tmr0c,a

; timer mode and prescaler set to /2

; setup interrupt register

mov a,00dh

; enable master interrupt and both timer interrupts

mov intc0,a

set tmr0c.4

; start Timer 0
