Preliminary—Subject to Change Without Notice

Overview

Freescale Semiconductor

— Modified SPI mode for interfacing to peripherals with longer setup time requirements

•

Support for up to 60 Mbit/s in Slave Only Rx mode

1.4.15

Serial communication interface module (LINFlex)

The LINFlex on this device features the following:

•

Supports LIN Master mode, LIN Slave mode, and UART mode

•

LIN state machine compliant to LIN1.3, 2.0, and 2.1 specifications

•

Manages LIN frame transmission and reception without CPU intervention

•

LIN features

— Autonomous LIN frame handling

— Message buffer to store as many as 8 data bytes

— Supports messages as long as 64 bytes

— Detection and flagging of LIN errors (Sync field, delimiter, ID parity, bit framing, checksum

and time-out errors)

— Classic or extended checksum calculation

— Configurable break duration of up to 36-bit times

— Programmable baud rate prescalers (13-bit mantissa, 4-bit fractional)

— Diagnostic features (Loop back, LIN bus stuck dominant detection)

— Interrupt-driven operation with 16 interrupt sources

•

LIN slave mode features

— Autonomous LIN header handling

— Autonomous LIN response handling

•

UART mode

— Full-duplex operation

— Standard non return-to-zero (NRZ) mark/space format

— Data buffers with 4-byte receive, 4-byte transmit

— Configurable word length (8-bit, 9-bit, or 16-bit words)

— Configurable parity scheme: none, odd, even, always 0

— Speed as fast as 2 Mbit/s

— Error detection and flagging (parity, noise, and framing errors)

— Interrupt-driven operation with four interrupt sources

— Separate transmitter and receiver CPU interrupt sources

— 16-bit programmable baud-rate modulus counter and 16-bit fractional

— Two receiver wake-up methods

•

Support for DMA-enabled transfers
