Bidirectional
BiSS
sensor communication with up to 3 slaves
Supports SSI protocol for unidirectional communication
Synchronous sensor data acquisition with cyclic transfer at
data rates of up to 10 Mbit/s
Command and slave register operations during cyclic data
transfers
Data lengths of up to 64 bits for sensor data, independently
scalable for each slave
Automatic compensation of line delays, measurement and
conversion times
Data verification by CRC polynomials of up to 8 bits, adjust-
able per slave
Separate memory banks enable free controller access during
BiSS
sensor data transfers
32 bytes of intermediate memory to ease bidirectional slave
register communications
Parallel controller interface with an 8-bit data/address bus
services Intel and Motorola devices
