4.1. USER INTERFACE
The EDK provides three buttons for influencing the operation of the board. The purpose of each button is clearly marked next
to it. Refer to the board layout for positions (Section 3)
1.
This button provides the microcontroller with a timed reset pulse of at least 250mS.
2.
This button toggles the operating mode of the microcontroller. A complete description of this function is given in
section 5.7.
3.
This button provides a de-bounced signal to the microcontroller for each operation of the button. There is no minimum or
maximum activation time for this button.
4.2. S
The serial interface on the EDK board has several functions. The serial port on the microcontroller directly supports three
wire serial interfaces. Options are provided on the board for the user to write handshaking routines using standard port pins.
Other board option links allow users to control the entry and exit from boot mode using the same handshaking signals. Refer
to section 5 for details on setting serial interface options.
4.2.1.
The EDK RS232 interface conforms to Data Communication Equipment (DCE) format allowing the use of 1-1 cables when
connected to Data Terminal Equipment (DTE) such as an IBM PC. The cable used to connect to the EDK will affect the
available board options. A fully wired cable can allow handshaking between the microcontroller and the host PC, subject to
setting the board options and the availability of suitable host software. Handshaking is not supported as standard on the
microcontroller so for normal use a minimal three-wire cable can be used. The minimum connections are unshaded in the
following table.
* These are not connected on the EDK by default. See section 5.4 for more details.
