An input/output attribute of PCM4202's I/O pin (Pin#16, Pin#17).

Other Parts Discussed in Thread: PCM4202

Dear All,

About PCM4202,

would you tell me about I/O Pin's input/output attribute in the specific situation?

■When user change Slave/Master in the operation of the PCM4202 using S/M Pin (Pin#8).

How becomes an operation of PCM4202 and an I/O Pin(Pin#16&17)'s input/output attribute?

Which of [1] ~ [3] is right?

[1]PCM4202 continues operating with a mode (Slave or Master) before toggled S/M Pin.

[2]The opertion of PCM4202 stops, but the input/output attribute of I/O pin (Pin#16&17)

maintains the state (Slave or Master) before the toggle of S/M Pin.

[3]The operating mode of PCM4202 is replaced immediately, and the input/output attribute

of I/O pin changes, too.

■When user reset the PCM4202 using RST Pin (Pin#19).

Is I/O Pin (Pin#16&17) before initialization being completed ....

[1]latched to "High"?

[2]latched to "Low"?

[3]"Hi-Z"?

Best Regards,

Tsuguhiko Asai
