3. STC (Standard Conversion) Command
Input of the STC command executes A/D conversion of the specified channel once.
Impletion of A/D conversion, the ENDC signal rises while the IRQX signal falls. Clock input to the SCK pin after
A/D conversion outputs data to the SOT pin. Upon completion of data output, the ENDC signal falls while the
IRQX signal rises. If the next command is STOP or NOP the A/D conversion is terminated. If the STC command
is input during A/D conversion, the command currently being executed is cancelled and the STC command is
executed.
Example of STC command execution (1)
STC command input during A/D conversion cancels the current command and executes A/D conversion of the
new specified channel. Output data at this time is 0000H.
Example of STC command execution (2)
NOP command input during A/D conversion does not affect operation. Output data at this time is 0000H. If A/
D conversion is completed during NOP command input, the ENDC and IRQX pin levels become “H” and “L”
respectively upon completion of the NOP command input.
