Programmable Interrupt Timer (PIT)
21.7.3 PIT Counter Modulo Registers
The read/write PIT modulo registers contain the modulo value for the PIT counter. When the PIT counter
reaches the modulo value the overflow flag (POF) becomes set and the PIT counter resumes counting
from $0000 at the next timer clock. Writing to the high byte (PMODH) inhibits the POF bit and overflow
interrupts until the low byte (PMODL) is written. Reset sets the PIT counter modulo registers.
