According to the documentation of "Read Parameter Page", byte 129-130, SDR modes 0 to 5 should be supported (page 19 on the data sheet). But the documentation of the GET_FEATURE/SET_FEATURE operation misses the "Timing mode" register (data sheet, page 24). I saw that there is a quirk for some Macronix chips which also seem not to support getting/setting the timing mode (but declaring them in the parameter page). My main question is whether this is "normal variation within the flash market" or a serious issue. In contrast to another device I currently use, the Foresee chip also doesn't support "cached" operations. Is there much value writing a fix for Timing Mode issue, or should I better use another flash device? regards, Christian
