Stop of Clock
MCLK can be stopped when PMMIC=PMADC=PMDAC=PMSPK= “0”.
1. When X’tal is used in PLL mode
MCKPD bit
(Addr:01H, D7)
PMXTL bit
(Addr:01H, D6)
PMPLL bit
(Addr:01H, D5)
MCKO bit
(Addr:03H, D4)
(1)
(2)
Example :
Audio I/F Form at : I
2
S
BICK frequency at Master Mode : 64fs
Input Master Clock Select at PLL Mode : 11.2896MHz
(1) Addr:04H, Data:62H
(2) Addr:01H, Data:80H
Figure 41. Stop of Clock Sequence(1)
<Example>
(1) Disable MCKO output : MCKO bit = “1”
“0”
(2) Power down X’tal and PLL, Pull down the XTI pin :
PMXTL bit = PMPLL bit = “1”
“0”, MCKPD = “0”
“1”
2. When an external clock is used in PLL mode
MCKPD bit
(Addr:01H, D7)
External MCLK
PMPLL bit
(Addr:01H, D5)
MCKO bit
(Addr:03H, D4)
Input
(1)
(2)
(3)
Example :
Audio I/F : I
2
S
BICK frequency at Master Mode : 64fs
Input Master Clock Select at PLL Mode : 11.2896MHz
(1) Addr:04H, Data:62H
(2) Addr:01H, Data:80H
(3) Stop external clock
Figure 42. Stop of Clock Sequence(2)
<Example>
(1) Stop MCKO output : MCKO bit = “1”
“0”
(2) Power down PLL, Pull down the XTI pin : PMPLL bit = “1”
“0”, MCKPD = “0”
“1”
When the external MCLK becomes Hi-Z or the external MCLK is input by AC couple, MCKI pin should be
pulled down.
(3) Stop an external MCLK
