Note: The buffers on UART0_TXD, UART0_RTS* and UART1_TXD are there to prevent connected
devices from changing the pin state during power-on. These pins are associated with SoC

Notes:
1. In the Direction column, Output is from Orin module. Input is to Orin module. Bidir is for Bidirectional signals.
2. The direction indicated for the CAN signals are associated with that usage. The pins support GPIO functionality, so support both
input and output operation (bidirectional).
