S12 Clock, Reset and Power Management Unit (S12CPMU)
7.3.2.17
The CPMUAPIRH and CPMUAPIRL registers allow the configuration of the autonomous periodical
interrupt rate.
Read: Anytime
Write: If APIFE=0, then write anytime, else writes have no effect.
The period can be calculated as follows depending on logical value of the APICLK bit:

APICLK=0: Period = 2*(APIR[15:0] + 1) * f
APICLK=1: Period = 2*(APIR[15:0] + 1) * Bus Clock period
