5.9.1 Crystal Oscillator
CKI and CKO can be connected to make a closed loop crys-
tal (or resonator) controlled oscillator.

5.9.2 R/C Oscillator
By selecting CKI as a single pin oscillator input, a single pin
R/C oscillator circuit can be connected to it. CKO is available
as a general purpose input, and /or HALT restart input.
Table 2 shows the variation in the oscillator frequency as a
function of the component (R and C) value.
