The kit demonstrates a simple interface design between the HI-3585, the HI-3598 or HI-3599 and a Freescale MC9S12XD64 microcontroller. The C code routines are shown as examples of how a user may program the Holt devices by setting up control registers, transmitting internal/external self test data, polling the status register, and retrieving received ARINC 429 data from each of the enabled receivers.
