MOTOROLA
Standard Space Vector Modulation with Dead-Time Correction TPU Function Set (svmStdDt)
TPU function svmStdDt_bottom generates an interrupt when the current values
of Ualfa, Ubeta , 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 bit 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.
