PLL Slave Mode 1
(PLL Reference Clock: MCKI pin)
PLL Slave Mode 2
(PLL Reference Clock: FCK or BICK pin)
EXT Slave Mode

Invalid state (Note 36)
0
Table 1. Clock Mode Setting (X: Don’t care)
Note 36. If this mode is selected, the invalid clocks are output from MCKO, FCK and BICK pins.

[Pull-down resistor of MCKI pin]
When the master clock is input, MCKPD bit should be
“

”
. When the MCKI pin is floating, the pin should be pulled-down
by internal 25k
resistor at MCKPD bit =
“
