Abstract

A microcontroller system transfers data between a memory stack and a plurality of general-purpose registers listed in an instruction in a single instruction cycle. An address generation circuit automatically generates register addresses only for those registers involved in the transfer. The stack pointer is modified or updated for each transfer.
