essor Interface 8-bit Data Bus ARINC Interface: “1” and “0” Lines, RZ Code Software Label Control in A Mode Parity Control: Odd or No Parity Interrupt Capability in A Mode Test Mode Capability Description The EF4442 is a reception interface for 4 ARINC 429 channels. Two models of operation are provided: • When in A mode, the circuit can be considered as a peripheral of an EF 6800 or EF6802 microprocessor and is totally software programmable (for example, for test purposes). When in B mode, the parameters are hardware programmed. Reading the registers which contain messages is only possible (max. scan frequency: 2 MHz).
