ST7FLCD1

8-bit Analog-to-Digital Converter (ADC)

CONTROL/STATUS REGISTER (ADCCSR)

Read/Write

Reset Value: (00h)

Bit 7 = COCO Conversion Complete

This bit is set by hardware. It is cleared by software by reading the result in the DR register or writing

to the CSR register.

Conversion is not complete (default)

Conversion can be read from the DR register.

Bit 6 = Reserved. This bit must be cleared by software.

Bit 5 = ADON A/D converter On

This bit is set and cleared by software.

A/D converter is switched off (default)

A/D converter is switched on

Note:

Remember that the ADC needs time to stabilize after the ADON bit is set.

Bits [4:2] = Reserved. Forced to 0 by hardware.

Bits [1:0] = CH[1:0] Channel Selection.

These bits are set and cleared by software. They select the analog input to be converted.

DATA REGISTER (ADCDR)

Read Only

Reset Value: (00h)

Bits [7:0] = AD[7:0] Analog Converted Value.

This register contains the converted analog value in the range 00h to FFh.

Reading this register resets the COCO flag.
