Also added SFR_SMI_REG_U16. Doing pval = reg_h; pval <<= 8; pval |= reg_l; dont always optimized by the compiler a some places, not all. A snipped of the diff between two .asm files. 5414,5424c5414,5416 < ; rtlplayground.c:1382: uint16_t pval = SFR_DATA_8; < ; rtlplayground.c:1383: pval <<= 8; < mov r7,_SFR_DATA_8 < mov r6,#0x00 < ; rtlplayground.c:1384: pval |= SFR_DATA_0; < mov r4,_SFR_DATA_0 < mov r5,#0x00 < mov a,r6 < orl ar4,a < mov a,r7 < orl ar5,a --- > ; rtlplayground.c:1382: uint16_t pval = SFR_DATA_U16; > mov r6,((_SFR_DATA_U16 >> 0) & 0xFF) > mov r7,((_SFR_DATA_U16 >> 8) & 0xFF)
