Detailed Description

The Spc700 class represents the SPC700 processor.

The Spc700 class provides the functionality to execute instructions, read and write memory, and handle various addressing modes. It also contains registers and flags specific to the SPC700.

Note: This class assumes the existence of an AudioRam object for memory access.
