Section 21 Serial I/O with FIFO (SIOF)
This LSI includes a single channel of clock-synchronized serial I/O module with FIFO (SIOF).
The SIOF is a module dedicated to the audio CODEC interface. Therefore, the SIOF is not
suitable for the applications other than the audio CODEC interface.
21.1 Features
• Serial transfer
16-stage 32-bit FIFOs (transmission and reception are independent of each other)
Supports 8-bit data/16-bit data/16-bit stereo audio input/output
MSB first for data transmission
Supports a maximum of 48-kHz sampling rate
Synchronization by either frame synchronization pulse or left/right channel switch
Supports CODEC control data interface
Connectable to linear, audio, or A-Law or µ-Law CODEC chip
Supports both master and slave modes
• Serial clock
An external pin input or internal clock (Pφ) can be selected as the clock source.
• Interrupts: One type
• DMA transfer
Supports DMA transfer by a transfer request for transmission and reception
