The REMC module input/output pins (REMI, REMO) are shared with general purpose input/output port pins
(P04, P05) and are initially set as general purpose input/output port pins. The function must be switched using the
P0_PMUX register setting to use general purpose input/output port pins as REMC input/output pins. Switch the
pins to REMC input/output by setting the following control bits to 1.
P04 → REMI
∗ P04MUX: P04 Port Function Select Bit in the P0 Port Function Select (P0_PMUX) Register (D4/0x52a0)
P05 → REMO
∗ P05MUX: P05 Port Function Select Bit in the P0 Port Function Select (P0_PMUX) Register (D5/0x52a0)
For detailed information on pin function switching, refer to "10.2 Input/output Pin Function Selection (Port
