Connecting the Serial Communication

The product communicates with the UART via the serial communication connectors. There are three serial
communication connectors: CN4, CN6, and CN7. Table 6.5 lists their pin assignments. Use CN7 when using a tool such
as waveform display in conjunction with the INV-BRD.

Connector No.
CN4
SCI0-1
CN6
SCI0-2
CN7
SCI2
Note 1. If you want to use this function, please be set to 1 PIOR01 bit of PIOR0 register.
Note 2. This port is, because of the Z-phase (ENC-Z) function and shared, can't be used in the factory
state.

Hall Sensor Signal Input

The product is equipped with a Hall sensor signal input connector. Using this connector it is possible to input the Hall
sensor signal from the motor supplied with the Motor RSSK directly to the product. The signal input to the product is
pulled up to 5 V and passed through an RC filter before being input to the RL78/G1F. Table 6.6 lists the pin
assignments of the Hall sensor signal input connector, and Table 6.7 lists connector information.
