Several additional functions are available on the multi function ports, see
features known from QuadFALC
selected (SYPR or SYPX) with exception of the ports RPC were RCLK output is
selected: The register bits PC3.RPC2 have the reset value F
be set to ´1´ for an active RCLK output. After reset PC5.CRP is ´0´ and RCLK is pulled
up.)
Three multi function ports (MFP) for RX - so called as RPA, RPB, RPC - and two MFPs
for TX - so called as XPA, XPB - are implemented for every channel. The port levels are
reflected in the appropriate bits of the register MFPI.
The actual logical state of the 5 multifunction ports can be read out using the register
MFPI. This function together with static output signal optins in
purpose I/O functionality on unused multi function port pins.
If a port is configured as GPOH or GPOL the port level is set fix to high or low level
respectively.
Each of the input functions may only be selected once. No input function must be
selected twice or more.
