ROM/Flash Initialization

5-15

There are two methods of injecting code into the Flash in bank A:

1. In-circuit programming

2. Loading it from ROM/Flash bank B

For the second method, hardware must direct the Falcon chip set to map 
the FFF00000-FFFFFFFF address range to Flash bank B following a hard 
reset. Bank A then can be programmed by code from bank B.

Software can determine the mapping of the FFF00000-FFFFFFFF address 
range by examining the rom_b_rv bit in the Falcon’s Rom B Base/Size 
register.
