sorry cannot use API as we are low level assembly. not C, need detail on interface so can program raw, it seems a lot of low level techincal information is missing to enable anyone to program this device. At a guess the feature engine must be a microprocessor of some type and the bits that are exposed in the doco are just register configs for 26 parameters, ie as per previous text, is the feature engine code in by default on power up or must all the code be loaded which from other comments in more that 26 parameters. 1. how do the undocumented paging registers really work 2. we are SPI interface so need example of reading and writing to 0X5E and sub registers etc 3. more detail on feature engine code etc. thanks
