Datasheet

Communications
Serial
communications
interface (SCIB)
• 3 channels
Serial communications modes:
• Asynchronous, clock synchronous, and smart-card interface
• Multiprocessor communications
• On-chip baud rate generator allows selection of the desired bit rate
• Choice of LSB-first or MSB-first transfer
Noise cancellation (only available in asynchronous mode)
I2C bus interface
(RIIC)
• 1 channel
Communications formats:
• I2C bus format/SMBus format
• Master/slave selectable
CAN module
(CAN)
(as an optional
function)
• 1 channel
• 32 mailboxes
Communications
Serial peripheral
interface (RSPI)
• 1 unit
RSPI transfer facility
• Using the MOSI (master out, slave in), MISO (master in, slave out),
SSL (slave select), and RSPI clock (RSPCK) signals enables serial
transfer through SPI operation (four lines) or clock-synchronous
operation (three lines)
• Capable of handling serial transfer as a master or slave
Data formats
• Switching between MSB first and LSB first
• The number of bits in each transfer can be changed to any number of
bits from 8 to 16, or to 20, 24, or 32 bits.
• 128-bit buffers for transmission and reception
• Up to four frames can be transmitted or received in a single transfer
operation (with each frame having up to 32 bits)
Buffered structure
• Double buffers for both transmission and reception
LIN module (LIN)
• 1 channel (LIN master)
• Supports revisions 1.3, 2.0, and 2.1 of the LIN protocol
