20 / 28 page SyncMOS Technologies Inc. SM89S16R1 8-Bits Micro-controller With 64KB Flash ROM & IKB RAM & RTC & ADC & PWM & PDWU embedded Specifications subject to change without notice contact your sales representatives for the most recent information. SM89S16R1 V1.0 JANUARY 2005 20 Internal Data memory The data memory of SM89S16R1 consists of 1024 bytes internal data memory (256 bytes standard RAM and 768 bytes AUX-RAM). The AUX-RAM is enable by SCONF.1 ($BF.1), and read/write by MOVX Analog to Digital Converter (ADC) The ADC block diagram was shown as below: Those are only 4 pins mirror to Port 2[7:4] at Vin<3:0>. The digital output DATA [11:4] were put into ADCD ($8FH). And the ADC interrupt vector is 4BH. The ADC SFR shown as below: ADSCR ($8EH) Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 Com Con ADCSS1 ADCSS0 CH1 CH0 COM: Read only. When conversion complete, it will be set. CON: when set, the ADC will conversion continuous, else it will conversion only once. ADCSS [1:0]: ADC clock select. (ADC_CLK range 500 KHz~2.5 MHz).If over frequency of ADC_CLK, the conversion data may be unstable. ADCSS1 ADCSS0 ADC_CLK 0 0 FOSC/8 0 1 FOSC/16 1 0 FOSC/32 1 1 FOSC/64 CH [1:0]: ADC channel select.
