4-BIT MICRO-CONTROLLER FOR LCD PRODUCT
TIMER/COUNTER FUNCTION
Each timer/counter can execute the timer function independly.
TIMER MODE
For timer mode ,timer/counter increase one at any rising edge of internal pulse . User can choose 4 kinds
of internal pulse rate by setting IPSB for timerB (IPSA for timerA).
When timer/counter counts overflow, TRGB (TRGA) will be generated to interrupt control unit.
PROGRAM EXAMPLE: To generate TRGA interrupt request after 60 ms with system clock XlN=32K Hz

NOTE:
The preset value of timer/counter register is calculated as following procedure.
Internal pulse rate: XIN/2
5
; XIN = 32KHz
The time of timer counter count one = 2
5
/XIN = 32/32K=1ms
The number of internal pulse to get timer overflow = 60 ms/ 1ms = 60 = 03CH
The preset value of timer/counter register = 1000H - 03CH = 0FC4H
INTERRUPT FUNCTION
There are 3 internal interrupt sources and 1 external interrupt source. Multiple interrupts are admitted
according the priority .
