This is fully supported by the processor HAL. Priority 7 corresponds to non-maskable interrupts and must be used with care: The acknowledge and configure macros are only relevant for external interrupts: By default it is active and enabled if the configuration contains the gprof profiling package, otherwise inactive. From Wikipedia, the free encyclopedia. The ColdFire instruction set is “assembly source” compatible by means of translation software available from the vendor and not entirely object code compatible with the Freescale MC3 Board Support.

The ColdFire instruction set is “assembly source” compatible by means procesor translation software available from the vendor and not entirely object code compatible with the Retrieved from ” https: The instructions are only 16, 32, or 48 bits long, a simplification compared to the series.
Timers 0 and 1 are never used by eCos so application code is free to manipulate these as required.
The MCF ColdFire Processor
This controls the support for gprof-based profiling. When compared to classic 68k hardware, the instruction set differs mainly in that it no longer has support for the binary-coded decimal BCD packed data format; it removes a number of other, less used instructions; and most instructions that are kept support fewer addressing modes. It should never be necessary to load mff5272 package explicitly. In turn the pin settings are mcc5272 to determine defaults for other hardware settings, for example which of the two on-chip uarts are usable.
The relevant code uses hardware timer 2, so that timer is no longer available for application code. It was formerly manufactured by Freescale Semiconductor formerly the semiconductor division of Motorola which merged with NXP in However, Fido has its own unique architecture and shares the instruction set with 68k only.
Freescale MC3 Board Support. Procfssor acknowledge and configure macros are only relevant for external interrupts: The MCF has a small instruction cache of bytes.
From Wikipedia, the free encyclopedia. Motorola-Freescale-NXP processors and microcontrollers. There is no data cache.
If the timer is required but a platform HAL provides an alternative implementation of the profiling support then this option can be disabled.
Usually the processor made to sleep, halting the cpu but leaving all peripherals active. This always uses hardware timer 3, proceasor should not be used directly by application code.
Also, floating point intermediates are 64 bits and not 80 bits as in the and coprocessors. If gprof-based profiling is in use then that will use hardware timer 2.
The default behaviour is to put the processor to sleep until the next interrupt. These options need to take into account the processor clock speed, a characteristic of the platform rather than the processor. Archived from the original on Priority 7 corresponds to non-maskable interrupts and must be used with care: Common manufacturer s NXP Semiconductors. InFreescale also launched Kinetis, an ARM -based product line, leading some industry observers  to speculate about the future of the ColdFire range, given that Freescale would have several competing CPU ranges.

The processor HAL provides support for the eCos system clock. It should be read in conjunction with similar sections from the architectural and variant HAL documentation. This uses hardware timer 2, so application code should not manipulate this timer if profiling is enabled.
