• Manufacturer Part Number: HD6417660
• Description: Renesas 32-Bit RISC Microcomputer
• Manufacturer: RENESAS [Renesas Technology Corp]

This LSI includes a clock-synchronized serial I/O module with FIFO (SIOF)(Serial Input/Output
with FIFO). The SIOF can perform serial communication with a serial peripheral interface bus
(SPI).
15.1
• Serial transfer
• Serial clock
• Interrupts: One type
• DMA transfer
• SPI mode
SCIS3F2D_000020020800
continuously.
16-stage 32-bit FIFOs (transmission is independent)
Supports 8-bit data/16-bit data/16-bit stereo audio 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
An external pin input or internal clock (Pφ) can be selected as the clock source.
Supports DMA transfer by a transfer request for transmission
Fixed master mode can perform the full-duplex communication with the SPI slave devices
Selects the falling/rising edge of the SCK as data sampling.
Selects the clock phase of the SCK as a transmit timing.
Selects three slave devices.
The length of transmit/receive data is fixed to 8 bits.
