45 / 97 page NuMicro NUC230/240 Datasheet Dec. 30, 2014 Page 45 of 97 Revision 1.01 6 FUNCTIONAL DESCRIPTION 6.1 ARM® Cortex™-M0 Core The Cortex™-M0 processor is a configurable, multistage, 32-bit RISC processor, which 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 6-1 shows the functional controller of processor. Cortex TM-M0 Processor Core Nested Vectored Interrupt Controller (NVIC) Breakpoint and Watchpoint Unit Debugger Interface Bus Matrix Debug Access Port (DAP) Debug Cortex TM-M0 processor Cortex TM-M0 Components Wakeup Interrupt Controller (WIC) Interrupts Serial Wire or JTAG Debug Port AHB-Lite Interface Figure 6-1 Functional Controller Diagram The implemented device provides the following components and features: A low gate count processor: - ARMv6-M Thumb ® instruction set - Thumb-2 technology - ARMv6-M compliant 24-bit SysTick timer - A 32-bit hardware multiplier - System interface supported with little-endian data accesses - 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 |
