• SLEEP

The SLEEP command shifts the LSI to a low power mode called “SLEEP mode”. The transition to the SLEEP

mode is carried out at the rising edge of CS after operation code in the SLEEP command. However, when

at least one SCK clock is inputted before the rising edge of CS after operation code in the SLEEP command,

this SLEEP command is canceled.

After the SLEEP mode transition, SCK and SI inputs are ignored and SO changes to a Hi-Z state.
