MFT1 and MFT2 Ports

The MB9B500 Serial MCU is embedded with two Multi-Function Timer (MFT) modules. This
reference provides two ports to output or input MFT control and feedback signals. The J2
port contains four parts: motor control, motor feedback, PFC control and PFC feedback. The
J6 contains two parts: motor control and feedback.
Table 4-1 shows the pin definition of J2.
