114 / 171 page  ST72260G, ST72262G, ST72264G 114/171 10-BIT A/D CONVERTER (ADC) (Cont’d) 11.7.6 Register Description CONTROL/STATUS REGISTER (ADCCSR) Read /Write (Except bit 7 read only) Reset Value: 0000 0000 (00h) Bit 7 = EOC End of Conversion This bit is set by hardware. It is cleared by soft- ware reading the ADCDRH register or writing to any bit of the ADCCSR register. 0: Conversion is not complete 1: Conversion complete Bit 6 = SPEED A/D clock selection This bit is set and cleared by software. Table 22. A/D Clock Selection (See Note 1) 1)The SPEED and SLOW bits must be updated before setting the ADON bit. 2)Use this setting only if f CPU ≤ 4 MHz Bit 5 = ADON A/D Converter on This bit is set and cleared by software. 0: Disable ADC and stop conversion 1: Enable ADC and start conversion Bit 4 = SLOW A/D Clock Selection This bit is set and cleared by software. It works to- gether with the SPEED bit. Refer to Table 22. Bit 2:0 = CH[2:0] Channel Selection These bits are set and cleared by software. They select the analog input to convert. DATA REGISTER (ADCDRH) Read Only Reset Value: 0000 0000 (00h) Bit 7:0 = D[9:2] MSB of Analog Converted Value DATA REGISTER (ADCDRL) Read Only Reset Value: 0000 0000 (00h) Bit 7:2 = Reserved. Forced by hardware to 0. Bit 1:0 = D[1:0] LSB of Analog Converted Value 70 EOC SPEED ADON SLOW 0 CH2 CH1 CH0 fADC Frequency SLOW SPEED fCPU (See Note 2) 0 1 fCPU/2 11 00 fCPU/4 1 0 Channel Pin CH2 CH1 CH0 AIN0 0 0 0 AIN1 0 0 1 AIN2 0 1 0 AIN3 0 1 1 AIN4 1 0 0 AIN5 1 0 1 70 D9 D8 D7 D6 D5 D4 D3 D2 70 000 000 D1 D0 |
