| 1 # This phone has 3 memory chip selects: | |
| 2 # | |
| 3 # nCS0: flash chip select 1 | |
| 4 # nCS1: RAM chip select | |
| 5 # nCS3: flash chip select 2 | |
| 6 # | |
| 7 # All 3 chip select lines go to the same physical IC, a RAM/flash MCP. | |
| 8 # We set WS=4 for all 3 here, copying what OsmocomBB does. The access | |
| 9 # time listed in the datasheet is 70 ns for both RAM and flash, and per | |
| 10 # my math setting WS=3 *might* work, but it could be marginal, so let's | |
| 11 # play it safe for now. | |
