PIT Load Bits 15:0 — These bits set the 16-bit modulus down-counter load value. Writing a new value into the
PITLD register must be a 16-bit access, to ensure data consistency. It will not restart the timer. When the timer
has counted down to zero the PTF time-out flag will be set and the register value will be loaded. The PFLT bits
in the PITFLT register can be used to immediately update the count register with the new value if an immediate
load is desired.
