(2) Channel select bits
A string of channel select bits selects the pin to be subject to A/D conversion. This bit string is enabled only for
the STC or ATC command.
*1: These settings of the bit string cause the STOP command to be executed.
*2: This setting is enabled only for the STC command. (See Section 5 “Port Input Command.”)
Upon completion of A/D conversion, the ENDC pin level becomes “H” and the IRQX pin level becomes “L.”
Execution of serial transfer at this time outputs data in the format illustrated below. The data output timing can
be selected by the MOD pin between the falling edge (mode A) or rising edge (mode B) of the SCK signal.
When the ENDC pin level is “L,” 0000H is output.
ENDC (A/D conversion completion flag): This bit is set to “1” upon completion of A/D conversion. It is set to
“0” upon completion of serial transfer.
Note: SCK input upon low-to-high transition of the ENDC pin level should be avoided. Otherwise, data may not
If this setting is made for the ATC command, the STOP command is executed.
