12.3.2 Three-phase/Port Output Switch Function
When the INVC03 bit in the INVC0 register set to 1 (Timer output enabled for three-phase motor control)
__
and setting the PFCi (i=0 to 5) in the PFCR register to 0 (I/O port), the three-phase PWM output pin (U, U,
__ ___
V, V, W and W) functions as I/O port. Each bit of the PFCi bits (i=0 to 5) is applicable for each one of
three-phase PWM output pins. Figure 12.37 shows the example of three-phase/port output switch func-
tion. Figure 12.38 shows the PFCR register and the three-phase protect control register.
