HI-3210
HI-3210 SYSTEM CONFIGURATION
Starting at memory address 0x8000, the HI-3210
contains a set of registers that are used to configure the
device.
The configuration registers are divided into three
categories, as follows;
1. HI-3210 global configuration
2. ARINC 429 Receive channel configuration
3. ARINC 429 Transmit channel configuration
The user needs only to program the HI-3210
configuration registers to completely define the full
system operation.
HI-3210 Global Configuration
The following registers define the HI-3210 top-level configuration:

A429RX
R/W
0
This bit must be set to a “1” to allow the HI-3210 to receiveARINC 429 data on any of the eight
channels. If set to a zero, the HI-3210 will not respond to any ARINC 429 receive bus,
regardless of the state of theARINC 429 Receive channel Control Registers.
6
A429TX
R/W
0
This bit must be set to a “1” to allow the HI-3210 to transmit ARINC 429 data on any of the four
channels. If set to a zero, the HI-3210 will not output ARINC 429 data and the ARINC 429
transmit sequencers will remain in their reset state.
