Reception & shift operationReception & shift operation
Notes 1. Only read received data while SWCm = 1 and before the next edge of the SCKp pin input is
detected.
2. The transfer end interrupt (INTCSIp) is cleared either when SWCm is cleared to 0 or when the
next edge of the SCKp pin input is detected.
Caution Before switching to the SNOOZE mode or after reception operation in the SNOOZE mode
finishes, be sure to set the STm0 bit to 1 and clear the SEm0 bit (to stop the operation).
Remarks 1. <1> to <10> in the figure correspond to <1> to <10> in Figure 12-75. Flowchart of SNOOZE Mode
