3-Phase Sine Wave Generator with Dead-Time Correction TPU Function Set (3SinDt) MOTOROLA
TPU function 3SinDt_bottom 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
bottom channels. The top channels do not generate any interrupts.
