 *
 *  Date Created: 2004.08.26
 *
 *  This source module implements a one-pass 8051 code disassembler customised to
 *  recognise the AT89c5131 SFR enhancements and to output SFR symbollic names in
 *  place of the respective direct addresses. All other address and data
 *  operands are output as hex numbers prefixed by a dollar sign ($xx).
 *
 *  The disassembler module takes about 5.5KB of program memory.
