Figure 43.

Block diagram of pin P4.4

When SALSEL = 10, 8-bit segment address lines are selected and P4.4 outputs the address. Any attempt

to use the CAN2 on P4.4 is masked. However, by enabling the I2C, the segment function is masked, pin

P4.4 is automatically configured as open-drain and used to input and output the SCL alternate function.

When CAN parallel mode is selected, CAN2_RxD is remapped on P4.5. This occurs only if CAN1 is also

enabled. If CAN1 is disabled, no remapping occurs.
