Description
7:0
PIT Micro Timer Load Bits 7:0
— These bits set the 8-bit modulus down-counter load value of the micro timers.
PMTLD[7:0] Writing a new value into the PITMTLD register will not restart the timer. When the micro timer has counted down
to zero, the PMTLD register value will be loaded. The PFLMT bits in the PITCFLMT register can be used to
immediately update the count register with the new value if an immediate load is desired.
