5.1
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 mode and Handler mode. 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.
Figure 5-1 shows the functional controller of processor.
The implemented device provides:
FUNCTIONAL DESCRIPTION
ARM
Interrupts
®
Cortex™-M0 Core
A low gate count processor that features:
Cortex-M0 components
Controller
Wakeup
Interrupt
The ARMv6-M Thumb® instruction set
Thumb-2 technology
ARMv6-M compliant 24-bit SysTick timer
A 32-bit hardware multiplier
The system interface supports little-endian data accesses
The ability to have deterministic, fixed-latency, interrupt handling
Load/store-multiples and multicycle-multiplies that can be abandoned and
restarted to facilitate rapid interrupt handling
C Application Binary Interface compliant exception model. This is the ARMv6-M,
C Application Binary Interface (C-ABI) compliant exception model that enables
the use of pure C functions as interrupt handlers
Low power sleep-mode entry using Wait For Interrupt (WFI), Wait For Event
(WFE) instructions, or the return from interrupt sleep-on-exit feature
(WIC)
