Note that two different simulated events can be used in the same step (like DS followed by ZS). Note also that for more precision, it is recommended to use the value captured from the preceding hardware event to compute the value used to generate simulated events. Figure 96, Figure 97 and Figure 98 shows details of simulated event generation. Figure 97. Simulated commutation event generation with only 1 hall effect sensor (SC bit = 1) 1. If the SC bit is set during Z event interrupt, then the 8*8 bit hardware multiplication result must be overwritten in the MCOMP register. Otherwise, when the SC bit is set, the result of the multiplication is not taken into account after a Z event. CH CH Z CS Z Z CS D C interrupt SC set in MCRC After C interrupt MCOMP is written for Cs event. If MCOMP ≤ MTIM immediate CS generation CS CS D C interrupt. SC reset in MCRB. Next C event = CH with 8*8 bit multiplication. t Z D CH CS Zero-crossing event Demagnetization event Hardware commutation Simulated commutation Obsolete Product(s) - Obsolete Product(s) |
