5.4.
The programming serial port is connected to the RS232 connector by default. This allows direct programming of the EDK
using the supplied software tools. A secondary serial port is available on the microcontroller and can be connected to the
RS232 connector by changing some board option links. The additional port option allows the user to write messages or
connect to other devices via the serial port while programming support is provided by the Flash programming header.
The following surface mount, zero-ohm link settings are fitted by default and connect the RS232 header to the programming
serial port of the microcontroller.
To enable the use of this alternate port the user must change the settings to those in the following table.
The user may implement a handshaking protocol on the EDK. This is not supported with the software tools supplied. To
support this option two spare port pins have been allocated on the microcontroller. Using these port pins the CTS and RTS
lines of the host serial interface can be controlled.
The user may also control the operation of the board via the same handshaking lines. This is not supported with the software
tools supplied but may be written by the user. Using the CTS line the user may simulate pressing the boot button, see
section:5.7. This will cause the EDK to swap into and out of Boot mode on each low-level activation of CTS. Feedback of the
current mode is provided on the RTS line. A high level indicates boot mode and a low level indicates user mode.
The following settings are made by default, and ensure that there are no conflicts on unnecessary microcontroller pins.
* See section 5.7
Note:
5.5. F
The Flash Programming header is used with the Hitachi Flash Debug Board (FDB). The FDB is a USB based programming
tool for control and programming of Hitachi microcontrollers, available separately from Hitachi. This header provides direct
access for the FDB to control the EDK microcontroller.
To utilise this header the user must make the following changes to the board configuration.

Caution: Do not operate the board with the user mode jumpers removed and the FDB disconnected as the
microcontroller mode pins will float to an indeterminate state. This may damage the microcontroller device.
Disable the RX232 signal from the RS232 transceiver.
Jumper link CJ4-A is provided for this purpose. Please refer to section5.3.
Disable User Program Mode using jumper CJ4-B. Please refer to section5.3.
