Read: Anytime
Write: Anytime if APIFE=0. Else writes have no effect.
The period can be calculated as follows depending on logical value of the APICLK bit:
4.38.3.2.18
Freescale Semiconductor
APIR[15:0]
Field
15-0
APICLK=0: Period = 2*(APIR[15:0] + 1) * f
APICLK=1: Period = 2*(APIR[15:0] + 1) * Bus Clock period
Autonomous Periodical Interrupt Rate Bits — These bits define the time-out period of the API. See
the effect of the autonomous periodical interrupt rate bits.
