Turn off ARINC 429 Transmit pins (Holds TXnA/B pins zero)
ARINC 429 Tx channel 0 data rate select output. 1 = high speed, 0 = low speed
ARINC 429 Tx channel 1 data rate select output. 1 = high speed, 0 = low speed
ARINC 429 Tx channel 2 data rate select output. 1 = high speed, 0 = low speed
ARINC 429 Tx channel 3 data rate select output. 1 = high speed, 0 = low speed
SPI chip select for auto-initialization EEPROM
SPI serial data input from auto-inialization EEPROM
SPI serial data output to auto-initialization EEPROM
SPI clock for auto-initialization EEPROM
Chip 0V supply
Chip select. Data is shifted into HMOSI and out of HMISO when HCSB is low
Host CPU SPI interface serial data output
Host CPU SPI interface serial data input
SPI Clock. Data is shifted into or out of the SPI interface using HSCLK
Master 48 MHZ and reference clock for ARINC 429 bus bit timing
Programmable event interrupt output
Programmable event interrupt acknowledge
MODE2 through MODE0 define HI-3210 start-up and initialization mode
Master Reset to HI-3210 Active High
Multiplexed with MODE0 pin, PROG initiates HI-3210 Auto-Initialization EEPROM programming routine
READY goes high when post-RESET initialization is complete
Master enable signal for ARINC 429 transmit schedulers
