Claim:
1. A power amplifier module comprising: one or more switches; a coupler module; a plurality of input signal pins configured to receive a plurality of input signals including at least a voltage input/output (VIO) signal, a clock input signal, and a data input signal; and a controller having at least first and second output terminals and configured, when the power amplifier module is in a first operating mode, to set a mode of the one or more switches using a synchronous communication protocol in which the controller outputs a synchronous clock signal on the first output terminal and a data signal on the second output terminal, the controller further configured, when the power amplifier module is in a second operating mode, to set a mode of the coupler module using an asynchronous communication protocol in which the controller outputs a first asynchronous control signal on the first output terminal and a second asynchronous control signal on the second output terminal.
