Hi Prabhakar, some updates after internal discussions I had. > +#define RPCIF_CMNCR_MOIIO_HIZ(val) (RPCIF_CMNCR_MOIIO0(val) | \ > + RPCIF_CMNCR_MOIIO1(val) | \ > + RPCIF_CMNCR_MOIIO2(val) | RPCIF_CMNCR_MOIIO3(val)) Shimoda-san rightfully said that '_HIZ' should be removed from the macro name because HIZ implies the value 3. > #define RPCIF_CMNCR_IO3FV(val) (((val) & 0x3) << 14) /* undocumented */ > #define RPCIF_CMNCR_IO2FV(val) (((val) & 0x3) << 12) /* undocumented */ As discussed before, mention here that they are documented for G2L. Sadly, we can't use them with Gen3... > -#define RPCIF_CMNCR_IOFV_HIZ (RPCIF_CMNCR_IO0FV(3) | RPCIF_CMNCR_IO2FV(3) | \ > - RPCIF_CMNCR_IO3FV(3)) > +#define RPCIF_CMNCR_IOFV_HIZ(val) (RPCIF_CMNCR_IO0FV(val) | RPCIF_CMNCR_IO2FV(val) | \ > + RPCIF_CMNCR_IO3FV(val)) ... which means we should remove this macro entirely because it is forbidden for Gen3. I think it is best to use the RPCIF_CMNCR_IOFV macros directly where we need them. Do you agree? Kind regards, Wolfram
