I Operation
3. Sleep Mode Setup
This section presents the procedure used to set the IC to sleep mode.
3. 1. Sleep mode overview
This IC operating clock can be stopped and the IC set to sleep mode by issuing a CKSP command to the
command register.
If the IC is processing path data internally, a CKSP command should only be issued after that processing has
completed. IC internal data is not guaranteed after a CKSP command is issued.
Sleep mode is released by issuing a CKST command to the command register. After clearing sleep mode, normal
mode operation can be restored by initializing the IC internally with the SRST command.
