Programmable Interrupt Timer Modules (PIT0–PIT3)
21.3
This section describes the PIT functional operation.
21.3.1 Set-and-Forget Timer Operation
This mode of operation is selected when the RLD bit in the PCSR register is set.
When the PIT counter reaches a count of 0x0000, the PIF flag is set in PCSRn. The value in the
modulus register is loaded into the counter, and the counter begins decrementing toward 0x0000.
If the PCSRn[PIE] bit is set, the PIF flag issues an interrupt request to the CPU.
When the PCSRn[OVW] bit is set, the counter can be directly initialized by writing to PMRn
without having to wait for the count to reach 0x0000.
21.3.2 Free-Running Timer Operation
This mode of operation is selected when the PCSRn[RLD] bit is clear. In this mode, the counter
rolls over from 0x0000 to 0xFFFF without reloading from the modulus latch and continues to
decrement.
When the counter reaches a count of 0x0000, the PCSRn[PIF] flag is set. If the PCSRn[PIE] bit is
set, the PIF flag issues an interrupt request to the CPU.
When the PCSRn[OVW] bit is set, the counter can be directly initialized by writing to PMRn
without having to wait for the count to reach 0x0000.
