Register description
Control/status register (ADCCSR)
Reset value: 0000 0000 (00h)
Bit 7 = EOC End of conversion bit
Bit 6 = SPEED ADC clock selection bit
Bit 5 = ADON A/D converter ON bit
Bit 4 = Reserved, must be kept cleared.
Bits 3:0 = CH[3:0] Channel selection
Table 55.
1. The number of channels is device dependent. Refer to the device pinout description.
Read only
EOC
This bit is set by hardware. It is cleared by hardware when software reads the ADCDRH
register or writes to any bit of the ADCCSR register.
0: Conversion is not complete
1: Conversion complete
This bit is set and cleared by software. It is used together with the SLOW bit to
configure the ADC clock speed. Refer to the table in the SLOW bit description
(ADCDRL register).
This bit is set and cleared by software.
0: A/D converter is switched off
1: A/D converter is switched on
These bits select the analog input to convert. They are set and cleared by software.
