BiSS Interface Master (2 channel / 8 slaves, RS422 transceiver, dual SPI)

iC-MB4 is a BiSS/SSI interface master controller.
An 8 bit bus or an SPI interface enable the communication with a µC.
Up to 8 BiSS slaves can be accessed: each SCD sensor data up to 64 bit and BiSS B/C register access and control communication.
Capturing is programmable by command, cycle time or external trigger.
Two RAM banks enable parallel access for the microcontroller while new sensor data is read in.
