LIN Sample Application for the MC68HC908EY16 Evaluation Board
A second method of using the monitor mode development environment is to
connect via the 16-pin P4 connector. This is configured for a Cyclone or
Multilink interface. Operation is very similar to that described above, the
advantage being that the users PCB does not need to incorporate an RS232
interface or a 9.8304MHz clock source. The high voltage for IRQ and the
appropriate levels on pins A1, B3 and B4 are also supplied by the interface so
no monitor mode hardware is required on the target hardware as long as these
pins are allowed to go to the required levels. Link J1 must be connected
between pin 1 (IRQ HIGH) and pin 2 (IRQ). All other links and the 9.8304MHz
canned oscillator module should be removed. The following procedure should
be used.
