René van Dorst bcf4ae316c fix SFR_DATA_U16: must use sfr a6a7 not sfr a4a5! 2025-09-01 16:47:57 +02:00
René van Dorst b8928a8bcd Replace manual SFR_DATA_0 and SFR_DATA_8 pair read and write with SFR_DATA_U16. 
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.

René van Dorst 9dafeab490 Added SFR_NIC_DATA_U16LE and SFR_NIC_RING_U16LE. 
Let's use sfr16 for NIC data and ring.
SFR define can so reordered to it does the BE to LE swap for us.

René van Dorst af0135bcce Add sfr16 SFR_REG_ADDR_U16. 
So instead do it manual split a uint16_t in to two uint8_t.
The compiler can do it, so reduces user error.
Note: compiler writes the lower/LSB part first.
      When that is importent this can´t be used.

Assembly is still the same except note above.
