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)

– module capability: maximum baud rate =

SYS / 4

– data frame length programmable from 1 to 63 bits

– MSB or LSB first

•

LIN Support (Local Interconnect Network)

– module capability: 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 (synchronous serial channel with or without data buffer)

– module capability: maximum baud rate =

SYS / 2, limited by loop delay

– 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)

– module capability: maximum baud rate =

SYS / 2

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

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

limited. Please note that there may be additional delays, such as internal or

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

mode, for IIC, etc.).
