0x0002
This subsection describes the PIT functional 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
PCSR. The value in the modulus latch is loaded into the counter, and the
counter begins decrementing toward 0x0000. If the PIE bit is set in
PCSR, the PIF flag issues an interrupt request to the CPU.
When the OVW bit is set in PCSR, the counter can be directly initialized
by writing to PMR without having to wait for the count to reach 0x0000.
