Data Control Instructions
Section 3-18
At the rising edge of W 000000 (OFF to ON), SETB(532) turns ON bit 15 of
D00209 (C+9) and starts autotuning. When autotuning is completed, the cal-
culated P, I, and D constants are written to C+1, C+2, and C+3. PID control is
then restarted with the new PID constants.
