CKS3 bit set to 1 (the AUDIO_X1 and AUDIO_X2 clocks are used), do not set the
MSTP4 bit to 1 (clock supply to the IEB except IECKSR is stopped). As for the setting
of the STBCR2 register, see section 27, Power-Down Modes.

These bits are always read as 0. The write value should
always be 0.
Input Clock Selection 3*
Specifies the clock the IEB uses
0: Peripheral clock (Pφ)
1: AUDIO_X1, AUDIO_X2
Reserved
This bit is always read as 0. The write value should
always be 0.
Input Clock Selection 2 to 0*
Specifies the division ratio for the clock IEB uses
000: IEB uses the clock of IEBφ specified by CKS3
001: IEB uses the 1/2 divided clock of IEBφ specified by
010: IEB uses the 1/3 divided clock of IEBφ specified by
011: IEB uses the 1/4 divided clock of IEBφ specified by
100: IEB uses the 1/5 divided clock of IEBφ specified by
101: IEB uses the 1/6 divided clock of IEBφ specified by
