MOTOROLA
OVW — Overwrite Bit
PIE — PIT Interrupt Enable Bit
PIF — PIT Interrupt Flag
RLD — Reload Bit
EN — PIT Enable Bit
Programmable Interrupt Timer Modules (PIT1 and PIT2)
The read/write OVW bit enables writing to PMR to immediately
overwrite the value in the PIT counter.
The read/write PIE bit enables the PIF flag to generate interrupt
requests.
The read/write PIF flag is set when the PIT counter reaches 0x0000.
Clear PIF by writing a 1 to it or by writing to PMR. Writing 0 has no
effect. Reset clears PIF.
The read/write RLD bit enables loading the value of PMR into the PIT
counter when the count reaches 0x0000.
The read/write EN bit enables PIT operation. When the PIT is
disabled, the counter and prescaler are held in a stopped state.
