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,
