Serial communication interface module (LINFlexD)

The LINFlexD module (LINFlex with DMA support) 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 50-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

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

–

2 receiver wake-up methods



Support for DMA enabled transfers
