Table 12-8 on page 145 shows the possible configurations.
 Bits 3:2 – CLKOUTSEL[1:0] : Clock Output Select
These bits are used to select which of the peripheral clocks will be output to the port pin if CLKOUT is configured.
 Bit 1:0 – CLKOUT[1:0]: Clock Output Port
These bits decide which port the peripheral clock will be output to. Pin 7 on the selected port is the default used. The
CLKOUT setting will override the EVOUT setting. Thus, if both are enabled on the same port pin, the peripheral clock will
be visible. The port pin must be configured as output for the clock to be available on the pin.
Table 12-10 shows the possible configurations.
