The default settings indicated in bold text place the microcontroller into operating Mode 3, i.e. on-chip ROM enabled, single
chip mode and clock mode 3: System clock = x4, Peripheral clock = x2.
5.3. EDK O
The EDK options provide access to commonly used features of the EDK range.
These jumpers must be fitted at all times to ensure correct operation of the EDK.
*
The following table lists the connections to each jumper pin.
5.4. S
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.
