5. Port Input Command
The port input command executes I/O evaluation of 8-channel inputs from the AN16 to AN23 pins at a prescribed
threshold in 10 clock cycles and outputs the results as port input data. The processing sequence is activated
each time port input is selected by the STC command. Port input data is output in the following format:
Evaluation data:
The evaluation values of AN23 to AN16 are output to bits Bf to B8.
Evaluation value
“H”: Vin
0.8 x Vcc
“L”: Vin
0.2 x Vcc
ENDC (A/D completion flag):
This bit is set to “1” upon completion of A/D conversion. It is set to “0” upon completion of serial transfer.
