8-BIT A/D CONVERTER (ADC) (Cont’d)
11.8.6 Register Description
CONTROL/STATUS REGISTER (CSR)
Read/Write
Reset Value: 0000 0000 (00h)
Bit 7 = COCO Conversion Complete
This bit is set by hardware when a conversion is
complete. It is cleared by software when reading
the CSR register.
0: Conversion is not complete
1: Conversion can be read from the DR register
Bit 6 = Reserved. must always be cleared.
Bit 5 = ADON A/D Converter On
This bit is set and cleared by software.
0: A/D converter is switched off
1: A/D converter is switched on
Bit 4 = Reserved. must always be cleared.
Bits 3:0 = CH[3:0] Channel Selection
These bits are set and cleared by software. They
select the analog input to convert.
*Note: The number of pins AND the channel selec-
tion varies according to the device. Refer to the de-
vice pinout.
