NuMicro^™ M058/M0516 Data Sheet
6 FUNCTIONAL DESCRIPTION
6.1 ARM® Cortex™-M0 Core
The Cortex^™-M0 processor is a configurable, multistage, 32-bit RISC processor. It has an AMBA AHB-
Lite interface and includes an NVIC component. It also has optional hardware debug functionality. The
processor can execute Thumb code and is compatible with other Cortex-M profile processor. The
profile supports two modes -Thread and Handler modes. Handler mode is entered as a result of an
exception. An exception return can only be issued in Handler mode. Thread mode is entered on Reset,
and can be entered as a result of an exception return.
