Periodic Interrupt Timer (S12PIT24B4CV1)
12.1
The period interrupt timer (PIT) is an array of 24-bit timers that can be used to trigger peripheral modules
or raise periodic interrupts. Refer to
12.1.1
12.1.2
The PIT includes these features:
12.1.3
Refer to the SoC guide for a detailed explanation of the chip modes.

micro time bases
Four timers implemented as modulus down-counters with independent time-out periods.
Time-out periods selectable between 1 and 2
cycles with 1 <= m <= 256 and 1 <= n <= 65536.
Timers that can be enabled individually.
Four time-out interrupts.
Four time-out trigger output signals available to trigger peripheral modules.
Start of timer channels can be aligned to each other.
