Table 2: COM Connections
COM Connector
A standard 9-pin Dsub connector provides external connections for the SCI port. The SCI port
provides an alternate interface for use with the MON08 monitor. Component U2 provides RS-
232 translation services. The figure below details the DB9 connector.
Figure 3: COM Connector
The communications mode of the COM port is determined by the COM_SEL jumper. This 3-
pin jumper allows the user to select between SCI serial communications and single-wire
MON08 communications.
Figure 4: COM_MODE Jumper
COM Select Jumper
The COM_SEL jumper selects between the RS-232 protocol or the LIN protocol on the MCU
SCI port.

MCU Pin
Female DB9 connector that interfaces to the HC08 internal SCI1 serial
port via the U2 RS232 transceiver. It provides simple 2 wire asynchro-
nous serial communications without flow control. Flow control is provided
at test points on the module.
Pins 1, 4, and 6 are connected together for NULL status to the host.
