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.
