Wireless Audio Module

FINAL

Note 2: GND: internally connected to the module ground plane. Every GND pin should be connected to the main PCB.ground plane.

NC: not connected.

TP: test point.

Note 3: All digital inputs have Schmitt trigger inputs. After reset all I/Os are set to input and all pull-up or pull-down resistors are enabled unless oth-

erwise specified.

PU = Pull-up resistor enabled, PD = Pull-down resistor enabled, I = input,

O = output, Hi-Z = high impedance, 1 = logic HIGH level, 0 = logic LOW level

Refer also to Px_DIR_REGs for INPUT/OUTPUT and Pull-up/Pull-down configurations
