4.4 CPU - Central Processing Unit
4.4.1 Introduction
The MPLAB® Code Configurator (MCC) Melody Central Processing Unit (CPU) system driver generates APIs to support CPU-specific peripheral functionality on PIC16 and PIC18 target MCUs.
This module supports the following functions:
- System arbitration which decides memory access allocation depending on user priorities
- Vectored interrupt capability with automatic two-level deep context saving
- 127-level deep hardware stack with overflow and underflow Reset capabilities
- Support Direct, Indirect, and Relative Addressing modes
- 8x8 hardware multiplier
