These bits can be used to pre-divide SYSCLK before it is output to a port pin through the
crossbar.
00: Output will be SYSCLK.
01: Output will be SYSCLK/2.
10: Output will be SYSCLK/4.
11: Output will be SYSCLK/8.
See Section “17. Port Input/Output” on page 183 for more details about routing this output to
a port pin.
RESERVED. Read = 0b. Must Write 0b.
000: SYSCLK derived from the high-frequency Internal Oscillator, and scaled as per the
