These are Input pins used on SACD-fsi Mode or SACD-fso Mode.
In case of no usage,from 47 pin to 53 pin should be tied to "low".
This function‘s detail explanation is shown in Page15 .
These are Input pins on "External sampling rate converter 8fs mode". In case of no usage ,
from 59 pin to 63 pin should be tied to "low" .
But when EXIOSEL is set the condition to "H" on no usage mode,
EXDATAL,EXDATAR are changed to output terminals for sampling rate converter.
This function‘s detail explanation is shown in Page14 .
XfsoIN pin is secondary master clock input.
The state of MCKSEL pin selects secondary master clock.
XfsoOUT pin is buffered-output from XfsoIN pin's input clock.
XfsiIN pin is primary master clock input.
Frequency of primary master clock must be selected by the serial control "System2 Mode,bit3".
The state of IMCKSEL pin selects primary master clock.
CKOUT1, CKOUT2 and CKOUT3 pins are divided-clock output from secondary clock.
At power on, these frequency is free-running.
The states of CKCTL1 and CKCTL2 pins selects clock frequency of CKOUT1,CKOUT2 and CKOUT3 pins.
The setting table of CKCTL1 and CKCTL2 pins is shown below.
FsoCKO is clock output pin of 1Fs frequency. The output is divided-clock of XfsoIN, and frequency is
free-running at power on. FsoCKO pin's clock is utilized for a synchronization in case that have used
plural M65817AFP,take a synchronization between M65817AFP and other external devices.
Detail explanation is shown in next paragraph, "SYNC ".
