The A/D start register (ADSR) is an 8-bit read/write register for starting and stopping A/D

conversion.

A/D conversion is started by writing 1 to the A/D start flag (ADSF) or by input of the designated

edge of the external trigger signal, which also sets ADSF to 1. When conversion is complete, the

converted data is set in the A/D result register (ADRR), and at the same time ADSF is cleared

to 0.

Bit 7—A/D Start Flag (ADSF): Bit 7 controls and indicates the start and end of A/D conversion.

Bit 7: ADSF
