Target Protocols

Each USIC channel can receive and transmit data frames with a selectable data word

width from 1 to 16 bits in each of the following protocols:

•

UART (asynchronous serial channel)

– maximum baud rate:

SYS / 4

– data frame length programmable from 1 to 63 bits

– MSB or LSB first

•

LIN Support (Local Interconnect Network)

– maximum baud rate:

SYS / 16

– checksum generation under software control

– baud rate detection possible by built-in capture event of baud rate generator

•

SSC/SPI/QSPI (synchronous serial channel with or without data buffer)

– maximum baud rate in slave mode:

SYS

– maximum baud rate in master mode:

SYS / 2

– number of data bits programmable from 1 to 63, more with explicit stop condition

– MSB or LSB first

– optional control of slave select signals

•

IIC (Inter-IC Bus)

– supports baud rates of 100 kbit/s and 400 kbit/s

•

IIS (Inter-IC Sound Bus)

– maximum baud rate:

SYS / 2 for transmitter, fSYS for receiver

Note: Depending on the selected functions (such as digital filters, input synchronization

stages, sample point adjustment, etc.), the maximum reachable baud rate can be

limited. Please also take care about additional delays, such as internal or external

propagation delays and driver delays (e.g. for collision detection in UART mode,

for IIC, etc.).
