2.3.36 PM4 / BF_PSYN / RXCAN0 / RXCAN4/ MOSI0 — Port M I/O Pin 4
PM4 is a general purpose input or output pin. It can be configured as the correct synchronisation pulse
reception/transmission output pulse pin of Byteflight. It can be configured as the receive pin RXCAN of
the Motorola Scalable Controller Area Network controllers 0 or 4 (CAN0 or CAN4). It can be configured
as the master output (during master mode) or slave input pin (during slave mode) MOSI for the Serial
Peripheral Interface 0 (SPI0).
