Receiver output of the LS CAN interface
This is an Input/Output pin.
This output is asserted LOW when an enabled interrupt condition occurs.
This pin is the tri-state output from the shift register.
This pin is for the input of serial instruction data.
This pin clocks the internal shift registers.
This pin communicates with the system MCU and enables SPI communication.
Input interfaces to external circuitry. Levels at these pins can be read by SPI and input
can be used as programmable wake-up input in Sleep or Stop mode.
