FRAM71B

[Sylvain Cote]

Hello Erwin,

Assuming you have followed my guide, you should have the following configuration

PEEK$("2C000",32) -> "D3E4D5D69798191A1B1C9D0000000000"

I would suggest to modify it for the following

POKE("2C000","D3E4D5D69798991A1B1C9D0000000000") / power cycle

Legend: CV=Configuration Value, CN=Chip Number, FB=FRAM Block

Code:

CV  CN  FB  Size  Type  Port  Description

D3   0   3  32KB  ROM   n/a   Translator 41 HC:E0000

1A   7   A  32KB  RAM   n/a   System RAM 128KB 1 of 4
1B   8   B  32KB  RAM   n/a   System RAM 128KB 2 of 4
1C   9   C  32KB  RAM   n/a   System RAM 128KB 3 of 4
9D   A   D  32KB  RAM   n/a   System RAM 128KB 4 of 4

With the above configuration, the FRAM block available (0, 1, 8, 9, E, F) for ROM image and the bank switching capability you can load all the ROMs.

Warning 1: Although it should work, I have not tested the following configuration.
Warning 2: The following commands will trigger on-the-fly bank-switching (OTF-BS) and if they contains LEX files they may cause a Memory Lost.
Dave is the expert here on OTF-BS, not me, yet , so do a backup of your data before playing with this.
