14. Three-Phase Motor Control Timer Function
Timers A1, A2, A4, and B2 can be used to output three-phase motor drive waveforms. Table 14.1 lists the
Three-phase Motor Control Timer Function Specifications. Figure 14.1 shows the Three-phase Motor Control
Timer Function Block Diagram. Figures 14.2 to 14.8 shows the Three-phase Motor Control Timer Function
related registers.

Forced cutoff with NMI input is effective when the IVPCR1 bit in the TB2SC register is set to 1 (three-phase
output forcible cutoff by NMI input enabled). If an “L” signal is applied to the NMI pin when the IVPCR1
bit is 1, the related pins go to a high-impedance state regardless of which functions of those pins are
being used.
