FUNCTIONAL DESCRIPTION
1.
SC (Serial Command) Register (Reset status: 0000H)
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.
(1) Command bits
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.
* :These command settings cause the STOP command to be executed.

ATC
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.”)
