10.8.20 PWM Output Disable Function
The microcomputer has the function to forcibly disable outputs from the P87(P00)/TO21–P82(P05)/TO26 and
P110(P10)/TO29–P115(P15)/TO34 that respectively are the output pins for the TOU0_0–TOU0_5 and TOU1_0–
TOU1_5 timers. This function may be used as a protective function when a fault condition such as short-circuiting
is detected during three-phase PWM control. This function can be used for all of output modes or port outputs of
TOU. However, use for other modes (external bus, SIO mode, DRI mode and TOP output modes (TO0-TO5) port
inputs) is prohibited. Figure 10.8.19 shows the circuit configurations of the PWM output disable function.
