ORDERING INFORMATION
HI - 3587 xx x x
SPI INTERFACE TIMING
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)
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
