Synopsis
Port Number: 1002
Function: Memory-mapped flash chip size.
Details
Bits [3:0]
Sets the flash chip size. 06 is the default (4 MB). 07 will map 8 MB, which will cause the 4 MB to be mirrored twice. 08 will attempt to map 16 MB, which has unknown effects but generally causes an instant crash. Smaller values map less flash, and will generally cause the OS to eventually freeze or crash.
Bits [7:4]
Writes have no apparent effect, value does not latch.
