Timer 2 clock select:
0 = Divide-by-6 clock
1 = Divide-by-12 clock
This bit has no effect if option bit 3 is set to 1 to select 12 clocks / machine cycle.

Stretch MOVX select bits: This bit is used to select the stretch value for the MOVX
instruction, which enables the microcontroller to access slower memory devices or
peripherals transparently and without the need for external circuits. The RD or WR
strobe and all internal timings are stretched by the selected interval. The default
value is 1 cycle. For faster access, set the value to 0.
CKCON has an unrestricted read access, however, the write access is protected by timed-access
protection. See the section of timed-access protection for more information.
