PIT Force Load Bits for Timer 7-0 — These bits have only an effect if the corresponding timer channel (PCE
set) is enabled and if the PIT module is enabled (PITE set). Writing a one into a PFLT bit loads the corresponding
16-bit timer load register into the 16-bit timer down-counter. Writing a zero has no effect. Reading these bits will
always return zero.
PIT Enable Bits for Timer Channel 7:0 — These bits enable the PIT channels 7-0. If PCE is cleared, the PIT
channel is disabled and the corresponding flag bit in the PITTF register is cleared. When PCE is set, and if the
PIT module is enabled (PITE = 1) the 16-bit timer counter is loaded with the start count value and starts down-
counting.
0 The corresponding PIT channel is disabled.
1 The corresponding PIT channel is enabled.
