Programmable Interrupt Timer Modules (PIT1 and PIT2)
14.6.2.2 PIT Modulus Register
Technical Data
288
Address: PIT1 — 0x00c8_0002 and 0x00c8_0003
The 16-bit read/write PIT modulus register (PMR) contains the timer
modulus value for loading into the PIT counter when the count reaches
0x0000 and the RLD bit is set.
When the OVW bit is set, PMR is transparent, and the value written to
PMR is immediately loaded into the PIT counter. The prescaler counter
is reset anytime a new value is loaded into the PIT counter and also
during reset. Reading the PMR returns the value written in the modulus
latch. Reset initializes PMR to 0xFFFF.
