PDS2–PDS0 — Prescaler Divisor Select Bits
PSSB4–PSSB0 — Clock Insertion Select Bits
Freescale Semiconductor
These read/write bits select the prescaler divisor as shown in
These read/write bits select the number of clocks inserted in each 32 output cycle frame to achieve
more timing resolution on the average prescaler frequency as shown in
PSSB4–PSSB0.
The setting of ‘000’ will bypass this prescaler. It is not recommended to
bypass the prescaler while ENSCI is set, because the switching is not glitch
free.
