ORDERING INFORMATION
HI - 3585 xx x x
SPI INTERFACE TIMING
RECEIVER TIMING
Delay - Last bit of received ARINC word to RFLAG(Full or Empty) - Hi Speed
Delay - Last bit of received ARINC word to RFLAG(Full or Empty) - Lo Speed
TRANSMITTER TIMING
Line driver transition differential times:
SPI transmit data write or FIFO clear instruction to TFLAG (Empty or Full)
(High Speed, control register CR10 = Logic 0)
(Low Speed, control register CR10 = Logic 1)
Received data available to SPI interface. RFLAG to
SPI receiver read or clear FIFO instruction to RFLAG
SPI instruction to ARINC 429 data output - Lo Speed
SPI instruction to ARINC 429 data output - Hi Speed
Delay TFLAG high after enable transmit - Lo Speed
Delay TFLAG high after enable transmit - Hi Speed
