PIT Enable Bits for Timer Channel 3:0 — These bits enable the PIT channels 3-0. 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.
