* : These command settings cause the STOP command to be executed.
SC (Serial Command) Register (Reset status: 0000H)
(1) Command bits
FUNCTIONAL DESCRIPTION
The SC register contains an A/D converter command and an input channel identification. Accessing this register
after releasing it from the reset status activates the A/D converter.
Note that this register accepts setting even during A/D conversion.
Note also that input of a command to the register must take an interval of at least 4 CCLKs after input of the
previous command.
A string of command bits selects an A/D converter command such as STOP . Setting a command during execution
of another command cancels the command currently being executed.

initializes the A/D converter. This command has the same
effect as RSTX.

No-op command. Input of this command during A/D
conversion does not affect operation. If followed by this
command, the ATC command can transfer converted data
while holding the NOP command.
The basic operation of this command is the same as that
of the STC command. The ATC command can leave the
A/D conversion start timing to the external trigger pin
ATGX. (See Section 4 “ATC (Auto Trigger Conversion)
Command.”)
