The board also incorporates a 9.8304MHZ canned oscillator module which is
required to run monitor mode using the RS232 PC interface. This module is
fitted using a socket so that it does not need to be fitted if it is not required.
Cyclone and Multilink interfaces incorporate their own clock source and thus do
not require the oscillator module.
There are pull-up resistors on the IRQ and Reset pins. Reset also has a pull-
down button and IRQ has a link that allows the connection of a zener stabilised
9 volts supply to enable entry into monitor mode which facilitates debugging
and in-circuit programming of the on-chip FLASH memory.
The board includes 5 LEDs driven directly by MCU port pins. These LEDs are
used in the monitor code to show that the application is running and to provide
some information on LIN bus activity.
