M054LAN Datasheet, PDF (19/64 Pages) Nuvotem Talema – ARM Cortex™-M0 32-BIT MICROCONTROLLER

64M052/M054 Data Sheet
„ 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.
NVIC features:
„ 32 external interrupt inputs, each with four levels of priority.
„ Dedicated non-Maskable Interrupt (NMI) input.
„ Support for both level-sensitive and pulse-sensitive interrupt lines
„ Wake-up Interrupt Controller (WIC), supports ultra-low power sleep mode.
Debug support:
„ Four hardware breakpoints.
„ Two watchpoints.
„ Program Counter Sampling Register (PCSR) for non-intrusive code profiling.
„ Single step and vector catch capabilities.
Bus interfaces:
„ Single 32-bit AMBA-3 AHB-Lite system interface that provides simple integration to all
system peripherals and memory.
„ Single 32-bit slave port that supports the DAP (Debug Access Port).
