- FUNCTION inp, outp, inpw, outpw, inpdw, outpdw
- DESCRIPTION
- IN/OUT port macros for byte and word ports, typically inlined by compilers
- which support these routines
- PARAMETERS
- inp( xx_addr )
- inpw( xx_addr )
- inpdw( xx_addr )
- outp( xx_addr, xx_byte_val )
- outpw( xx_addr, xx_word_val )
- outpdw( xx_addr, xx_dword_val )
- xx_addr - Address of port to read or write (may be memory mapped)
- xx_byte_val - 8 bit value to write
- xx_word_val - 16 bit value to write
- xx_dword_val - 32 bit value to write
- DEPENDENCIES
- None
- RETURN VALUE
- inp/inpw/inpdw: the byte, word or dword read from the given address
- outp/outpw/outpdw: the byte, word or dword written to the given address
- SIDE EFFECTS
- None.
- ===========================================================================*/

- ** macroized to access memory directly
