Digital Input/Outputs

The TCAN1164-Q1 has 6 digital I/O pins, four of which are used to implement the SPI communications and the other two are utilized for the TXD and RXD signals for the CAN. These digital I/Os operate on the VCCOUT pin. Four of these input pins have integrated pull-up resistors that weakly bias them.

The following sections provide the functional safety mechanisms that cover the digital inputs and outputs:
