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
