HT46R068B/HT46R069B

Enhanced A/D 8-Bit OTP MCU

A/D Programming Example

ThefollowingtwoprogrammingexamplesillustratehowtosetupandimplementanA/D

conversion.Inthefirstexample,themethodofpollingtheEOCBbitintheADCRregisterisused

todetectwhentheconversioncycleiscomplete,whereasinthesecondexample,theA/Dinterruptis

usedtodeterminewhentheconversioniscomplete.

Example: using an EOCB polling method to detect the end of conversion

clr EADI

; disable ADC interrupt

mov a,00000001B

mov ACSR,a

; select fSYS/8 as A/D clock and ADONB=0

mov a,0Fh

; setupANCSR0andANCSR1toconfigurepinsAN0~AN3

mov ANCSR0,a

mov a, 00h

mov ANCSR1,a

;

mov a,00000000B

;

mov ADCR,a

; select AN0 to be connected to the A/D converter

:

Start_conversion:

clr START

set START

; reset A/D

clr START

; start A/D

Polling_EOC:

sz EOCB

; poll the ADCR register EOCB bit to detect end

; of A/D conversion

jmp polling_EOC

; continue polling

mov a,ADRL

; read low byte conversion result value

movadrl_buffer,a ;saveresulttouserdefinedregister

mov a,ADRH

; read high byte conversion result value

movadrh_buffer,a ;saveresulttouserdefinedregister

:

jmp start_conversion ; start next A/D conversion
