Renesas 740

OVERVIEW

1) An efficient instruction set and many addressing modes allow the effective use of ROM.
2) The same bit management, test, and branch instructions can be performed on the Accumulator, memory, or I/O area.
3) Multiple interrupts with separate interrupt vectors allow servicing of different non-periodic events.
4) Byte processing and table referencing can be easily performed using the index addressing mode.
5) Decimal mode needs no software correction for proper decimal operation.
6) The Accumulator does not need to be used in operations using memory and/or I/O.
