Addressing Modes
The ’C3x supports five groups of powerful addressing modes. Six types of
addressing that allow data access from memory, registers, and the instruction
word can be used within the groups. This chapter describes the operation,
encoding, and implementation of the addressing modes. It also discusses the
management of system stacks, queues, and dequeues in memory.
