9.2.5 Remote Control Carrier Generator
The PA6/RMO pin functions as a general-purpose I/O port after reset. The RMPE bit must be set in order
to use this port as a remote control carrier output. The RMO outputs idle state is set by the RPOL bit when
RMON is cleared. The RMCLK signal selected by RMC4–RMC0 bits is output on the pin when RMON is
set.
