Table 13-7. Virtual port mapping.
13.14.4 CLKEVOUT – Clock and Event Out register
Bit 7:6 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always write these bits to zero
when this register is written.
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.
