MOTOROLA
Standard Space Vector Modulation – XOR version TPU Function Set (svmStdXor)
TPU function svmStdXor_R 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 R channels. The T channels do not
generate any interrupts.
