Clock is divided by 16.
CLKOUT enable control, allows switching the CLKOUT
source without glitches. Clear to stop CLKOUT on the
next falling edge. Set to enable CLKOUT.
CLKOUT activity indication. Reads as 1 when CLKOUT is
enabled. Read as 0 when CLKOUT has been disabled via
the CLKOUT_EN bit and the clock has completed being
stopped.
Reserved, user software should not write ones to reserved
bits. The value read from a reserved bit is not defined.
