AIF TDM AND TRI-STATE CONTROL
The AIFn output pins are tri-stated when the AIFn_TRI register is set. Note that, when a GPIOn pin is
configured as a GPIO, this pin is not affected by the respective AIFn_TRI register.
See “General
Purpose Input / Output
” to configure the GPIO pins.
Under default conditions, the AIFnTXDAT output is held at logic 0 when the WM8281 is not
transmitting data (ie. during timeslots that are not enabled for output by the WM8281). When the
AIFnTX_DAT_TRI register is set, the WM8281 tri-states the respective AIFnTXDAT pin when not
transmitting data, allowing other devices to drive the AIFnTXDAT connection.
