SERIAL AUDIO INTERFACE (SAI)
The SAI is composed of separate receiver and transmitter sections.

Signal Description
SDI0
Input
Tri-stated
Serial Data Input 0
—While in the high impedance
state, the internal input buffer is disconnected from
the pin and no external pull-up is necessary. SDI0 is
the serial data input for receiver 0.
Note:
This signal is high impedance during hardware or
software reset, while receiver 0 is disabled
(R0EN = 0), or while the DSP is in the Stop state.
SDI1
Input
Tri-stated
Serial Data Input 1
—While in the high impedance
state, the internal input buffer is disconnected from
the pin and no external pull-up is necessary. SDI1 is
the serial data input for receiver 1.
Note:
This signal is high impedance during hardware or
software reset, while receiver 1 is disabled
(R1EN = 0), or while the DSP is in the Stop state.
SCKR
Input or
Output
Tri-stated
Receive Serial Clock
—SCKR is an output if the
receiver section is programmed as a master, and a
Schmitt-trigger input if programmed as a slave. While
in the high impedance state, the internal input buffer
is disconnected from the pin and no external pull-up is
necessary.
Note:
SCKR is high impedance if all receivers are
disabled (individual reset) and during hardware or
software reset, or while the DSP is in the Stop state.
