Stop of Clock
Master clock can be stopped when ADC is not used.
1.
PLL Master Mode
External MCKI
PMPLL bit
(Addr:01H, D0)
MCKO bit
(Addr:06H, D2)
Input
(3)
(1)
(2)
"H" or "L"
M/S bit
(Addr:01H, D1)
Example:
Audio I/F Format: I2S
BCLK frequency at Master Mode: 64fs
Input Master Clock Select at PLL Mode: 11.2896MHz
Sampling Frequency: 44.1kHz
(2) Addr:06H, Data:00H
(1) Addr:01H, Data:10H
(3) Stop an external MCKI

<Example>
(1)
Power down PLL: PMPLL=M/S bits = “1”
→
“0”
(2)
Stop MCKO clock: MCKO bit = “1”
→
“0”
(3)
Stop an external master clock.
