These three bits determine the number of wait states (machine cycles) to
insert when accessing the USB SFRs:
000 = 0 (not to be used).

CKWT.1
001 = 1 wait state.
Use when MPU clock is <12MHz.
010 = 2 wait states. Use when MPU clock is between 12 and 16MHz.
011 = 3 wait states. Use when MPU clock is 24MHz.
100 = 4 wait states.
101 = 5 wait states.
110 = 6 wait states.
CKCON.0
CKWT.0
111 = 7 wait states.
