(pid1)
[0]
PID integral term accumulator
reset. Allows FW to reset the
accumulator by first writing a 1 to
reset the accumulator followed by
writing a 0 to release the reset.
0: Accumulator operating normally
1: Accumulator reset to 0

PID integral term accumulator
freeze control. Allows FW to hold
the accumulator at its current value
by writing a 1 until it is released by
writing a 0.
0: Accumulator operating normally
1: Accumulator value frozen
