How can I stop BCLK output in sleep mode or all-module clock stop mode?

Latest Updated:01/23/2014

Question:

I'm using BCLK. BCLK output does not stop even in sleep mode or all-module clock stop mode. How can I stop BCLK output in sleep mode or all-module clock stop mode?

Answer:

Although BCLK stops automatically in software standby mode and deep software standby mode and the BCLK pin is fixed high, it does not stop in sleep mode and all-module clock stop mode.

To stop the output of the BCLK pin in sleep mode or all-module clock stop mode, set the SCKCR.PSTOP1 bit to 1 before entering the mode.

For details, please see External Bus Clock in the Internal Clock section of the Clock Generation Circuit chapter of the User's Manual: Hardware.
