User manual
The I
channel. These support the NXP Inter IC Audio format for 8-bit, 16-bit and 32-bit audio
data, both for stereo and mono modes. Configuration, data access and control is
performed by a APB register set. Data streams are buffered by FIFOs with a depth of
8 words.
The I
mode. Within the I
(WS) signal which determines the timing of data transmissions. Data words start on the
next falling edge of the transmitting clock after a WS change. In stereo mode when WS is
low left data is transmitted and right data when WS is high. In mono mode the same data
is transmitted twice, once when WS is low and again when WS is high.

In master mode, word select is generated internally with a 9-bit counter. The half
period count value of this counter can be set in the control register.
In slave mode, word select is input from the relevant bus pin.
When an I
are sent continuously by the bus master, while data is sent continuously by the
transmitter.
Disabling the I
transmit and receive.
The stop bit will disable accesses by the transmit channel or the receive channel to
the FIFOs and will place the transmit channel in mute mode.
The mute control bit will place the transmit channel in mute mode. In mute mode, the
transmit channel FIFO operates normally, but the output is discarded and replaced by
zeroes. This bit does not affect the receive channel, data reception can occur
normally.
