PIT Time-out Flag Bits for Timer Channel 3:0 — PTF is set when the corresponding 16-bit timer modulus
down-counter and the selected 8-bit micro timer modulus down-counter have counted to zero. The flag can be
cleared by writing a one to the flag bit. Writing a zero has no effect. If flag clearing by writing a one and flag setting
happen in the same bus clock cycle, the flag remains set. The flag bits are cleared if the PIT module is disabled
or if the corresponding timer channel is disabled.
0 Time-out of the corresponding PIT channel has not yet occurred.
1 Time-out of the corresponding PIT channel has occurred.
