SFR16 Assembler Statement

Arguments

sfr16 sfr_symbol = address;

Description

The sfr16 statement defines a 16-bit Special Function Register (SFR) to the assembler.

Note

The Ax51 assembler ignores symbol definitions that start with sfr16. This is implemented to maintain compatibility with the Cx51 compiler.

Example

sfr16  T2 = 0xCC;   /* ignored by AX51  */
