22.3.2.32 Port M Data Direction Register (DDRM)
Read: Anytime.
Write: Anytime.
This register configures each port M pin as either input or output.
The CAN/SCI3 forces the I/O state to be an output for each port line associated with an enabled output
(TXCAN[3:0], TXD3). TheyAlso forces the I/O state to be an input for each port line associated with an
enabled input (RXCAN[3:0], RXD3). In those cases the data direction bits will not change.
The DDRM bits revert to controlling the I/O direction of a pin when the associated peripheral module is
disabled.
