ARINC receiver negative input. Direct connection to ARINC 429 bus
Alternate ARINC receiver negative input. Requires external 40K ohm resistor
Master Reset. A positive pulse clears the Receiver data FIFO and flags
SPI interface serial data input
Chip select. Data is shifted into SI and out of SO when
SPI Clock. Data is shifted into or out of the SPI interface using SCK
Chip 0V supply. Note BOTH GND pins MUST be connected
Master timing source for the ARINC 429 receiver
