The PUP command shifts from the power-down state to the command standby state.
Since only the PUP command is accepted when the LSI is in the power-down state, the command is ignored if another
command is input.
To return to the power-down mode, enter the PDWN command.
The WCM bit is used to set the mode for inputting command and data two-times. When this bit is set to "1", the subsequent
command and data inputs are set to the two-times input mode, and the command is accepted only when they match.
If they do not match, the accepted command is discarded. Refer to the "RDSTAT command", "OUTSTAT command", and
"SAFE command" for handling when a mismatch occurs.
Even if two-times input modes are used for the I
2
C interface, one-time input is used for the slave address input. If the slave
address matches, ACK is returned. If the slave address does not match, NACK is returned. The command is input two-times.
