Notes:
1) COM_SW position 4 and 7 should not be ON at the same time.
2) HCS08 device port pins PTE0/TXD1 and PTC0/TXD2 are applied to the COM1 and COM2
COM1
The COM1 port provides standard 9 pin connection with RS232 type interface to the HCS08
SCI1 peripheral. Refer to the COM SW for enabling the HCS08 RXD1 signal applied to this
port. The COM1 port is applied by default with the Monitor. The HCS08 TXD1 and RXD1
signals are converted to RS232 levels by U7 and provided to the COM1 connector. Following
is the DB9S connection reference.
COM1
COM SW position 1 will isolate the SCI1 RXD1 pin (PTE1) from the transceiver.
The 1,4,6,7,8, and 9 pins provide RS232 flow control and status. These are connected on the
on the bottom of the development board to provide a NULL status returned to the host. the
DB9 connector locations are provided access pads behind the connector. User may isolate
the connection pads by cutting the associated circuit trace on the bottom of the board. The
user may then apply flow control or status connections to the host by applying HCS08 I/O
signals and additional RS232 level conversion. COM2 provides these signals.
COM2
The COM2 port provides standard 9 pin connection with RS232 type interface to the HCS08
SCI2 peripheral. Note that COM2 is shared with the 422_485 serial port also. Following is the
DB9S connection reference.

The COM-1 port has a Female DB9 connector that interfaces to
the HCS08 internal SCI1 serial port via the U7 RS232
transceiver. It applies simple 2 wire asynchronous serial without
flow controls.
