Winbond ROMCON Register

Ekim Nosneb

Does anyone know the intended use for the ROMCON register in a Winbond W77L532?

I'm trying to figure out how to do code banking for it and the datasheet is unclear.

I'm thinking that I need to use B_MODE=4 and set EN128K and DCP10-DCP11 in the startup code. Then set P1.x to 0 or 1 accordingly when switching banks (in SWITCH0, SWITCH1, etc. macros).

I'd also be interested in any other information, examples, etc., specific to code banking with the W77L532.

Thanks.
