4.2 Board Control Registers
The Board Control registers may be accessed through byte-wide read and write operations.
4.2.1 Board ID Register
The Board ID is used to identify the VMP3 in a E²Brain™ system. The value for the VMP3 is
0x45 which is factory set and cannot be changed.
4.2.2 Software Compatibility ID
The Software Compatibility ID will signal to the software when differences in hardware require
different handling by the software. It starts with the value 0x00 and will be incremented with
each change in hardware (software sensitive only). This register is set at the factory and is for
use only by the boot strap loader “NetBootLoader” and the BSP software, and, as such, is not
user relevant.
