Clock Output

The clock output function select bit allows you to choose the clock from f8, fc, or a divide-by-n clock that is

output from the P54/CKOUT pin. The clock divide counter is an 8-bit counter whose count source is f32, and

its divide ratio can be set in the range of 0016 to FF16. Figure 1.19 shows a block diagram of clock output.
