Stop of Clock
Master clock can be stopped when ADC, DAC and programmable filter don’t operate.
1. PLL Master Mode
External MCKI
PMPLL bit
(Addr:01H, D0)
MCKO bit
(Addr:01H, D1)
Input
(3)
(1)
(2)
"H" or "L"
Example:
Audio I/F Format: DSP Mode, BCKP = MSBS = “0”
BICK frequency at Master Mode : 64fs
Input Master Clock Select at PLL Mode : 11.2896MHz
Sampling Frequency:8kHz
Stop an external MCKI
(1) (2) Addr:01H, Data:08H
Figure 57. Clock Stopping Sequence (1)
<Example>
(1) Power down PLL: PMPLL bit =
1
0
(2) Stop MCKO clock: MCKO bit =
1
0
(3) Stop an external master clock.
