3-Phase Sine Wave Generator – 3 outputs version TPU Function Set (3Sin3)
TPU function 3Sin3 generates an interrupt when the current values of Ampl,
dTheta (optionally also Theta), T and prescaler have been read by the TPU, and
indicates to the CPU that it can write new variables. The CPU program can
either wait for this interrupt to occur, or poll the LD_OK parameter to check it
has cleared. The interrupt is generated at each reload by one of the PWM
channels.
