Section 20 Serial IO (SIOF)
20.1 Overview
SIOF is a clock-synchronized serial I/O module that can be directly connected to the audio
CODEC.
20.1.1 Features
Feature of SIOF are listed below.
• Serial transmitting
⎯ 32 bit × 16 step sized FIFO for send or receive communication
⎯ 8 bit/16 bit/recording or playback function for 16 bit stereo sound
⎯ Both big endian and little endian are supported in data transmission and reception
⎯ Variable sampling rate up to 48 kHz
⎯ Synchronization corresponds to frame sync pulse and switching right/left channels
⎯ Support CODEC control function through data line
⎯ Support linear/audio A-Law and μ-Law CODEC chip
⎯ Support both master and receive communication mode
• Serial clock
⎯ External clock or peripheral clock (Pφ) may be used as clock source.
• Interrupt
It is possible to require independently the following 4 interruptions.
⎯ Transmit interrupt
⎯ Receive interrupt
⎯ Error interrupt
⎯ Control interrupt
• DMA transfer
⎯ Supports transmit/receive operations using DMA transfer in response to a transmit/receive
transfer request
