4. Converter Configuration Table Registers
This module contains all the configuration registers that the converter needs to operate.
Registers are referenced from @00 up to @FF.
There are two ways to access the configuration table registers:
- During the POR procedure, some registers can be preset to start the system as predetermined.
- Using the microprocessor interface, the configuration table register can be either READ or WRITE.
Write access to a read-only register is not valid and does not change the held value of that register.
All errors are logged (not first failure data capture).
All bits in configuration table registers are active binary 1.
The registers can be accessed either in 8-bit (byte) mode or in 32-bit (burst) mode through bursts of 4x 8-
bits modes (for I960 Processors). In 32-bit mode, the least significant byte is sent first, then the second
least significant byte, and so forth.
The registers are based on little endian notation.
