3.7.3.3 Host Block Muxing
This block of 27 pins consists of EMAC, MDIO, and GPIO muxed pins. The following register field selects
the pin functions in the Host Block:
• PINMUX1.HOSTBK
Table 3-21 summarizes the 27 pins in the Host Block, the multiplexed function on each pin, and the
PINMUX configurations to select the corresponding function.
