3.1.1 Hardware Connection

The host demo codes also use MSPM0 as the host MCU. The hardware signals connection between host and target is shown in Table 3-8

Note: Connect only one communication interface that UART or I2C or SPI. The target side pins are just default configuration pins that can be changed in the non-main flash.
Note: When use software invoke, the reset and invoke signals do not need to be connected.
Note: For CANFD, the transceiver are needed to connected with MSPM0 both host and target side.
