• Bit 3:0 – VP2MAP: Virtual Port 2 Mapping
These bits decide which ports should be mapped to Virtual Port 2. The registers DIR, OUT, IN,
and INTFLAGS will be mapped. Accessing the virtual port registers is equal to accessing the
actual port registers. See
for configuration.

CLKEVOUT – Clock and Event Out register
• Bit 7 – CLKEVPIN: Clock and Event Output Pin Select
Setting this pin enables output of clock and event pins on port pin 4 instead of port pin 7.
• Bit 6 – RTCOUT: RTC Clock Output Enable
Setting this bit enables output of the RTC clock source on PORTC pin 6.
• Bit 5:4 – EVOUT[1:0]: Event Output Port
These bits decide which port event channel 0 from the event system will be output to. Pin 7 on
the selected port is the default used, and the CLKOUT bits must be set differently from those of
EVOUT. The port pin must be configured as output for the event to be available on the pin.
