Section 18 Serial Sound Interface (SSI)
The serial sound interface (SSI) is a module designed to send or receive audio data interface with
various devices offering Philips format compatibility. It also provides additional modes for other
common formats, as well as support for multi-channel mode.
18.1 Features
• Number of channels: Four channels
• Operating mode: Non-compressed mode
The non-compressed mode supports serial audio streams divided by channels.
• Serves as both a transmitter and a receiver
• Capable of using serial bus format
• Asynchronous transfer takes place between the data buffer and the shift register.
• It is possible to select a value as the dividing ratio for the clock used by the serial bus interface.
• It is possible to control data transmission or reception with DMAC and interrupt requests.
• Selects the oversampling clock input from among the following pins:
EXTAL, XTAL (Clock operation modes 0 and 1: 10 MHz to 33.33 MHz)
CKIO (Clock operation mode 2: 40 MHz to 50 MHz*)
AUDIO_CLK (1 MHz to 40 MHz)
AUDIO_X1, AUDIO_X2 (crystal resonator connected: 10 MHz to 40 MHz;
external clock input: 1 MHz to 40 MHz)
Note: * Do not select CKIO as the source for the oversampling clock when using a CKIO
frequency exceeding 50 MHz in clock operation mode 2.
