The processor HAL provides support for the eCos system clock. It was formerly manufactured by Freescale Semiconductor formerly the semiconductor division of Motorola which merged with NXP in From Wikipedia, the free encyclopedia. In , Freescale also launched Kinetis, an ARM -based product line, leading some industry observers [18] to speculate about the future of the ColdFire range, given that Freescale would have several competing CPU ranges. The default behaviour is to put the processor to sleep until the next interrupt. It corresponds directly to the M68K exception number. 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.

When compared to classic 68k hardware, the instruction set differs mainly in that it mc5f272 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. However, Fido has its own unique architecture and shares the instruction set with 68k only.

Motorola-Freescale-NXP processors and microcontrollers. Retrieved from ” https: The acknowledge and configure macros are only relevant for external interrupts: Also, floating point intermediates are 64 bits and not 80 bits as in the and coprocessors.

Users can override these settings if necessary, subject to any constraints imposed by the platform HAL, but care has to be taken that the resulting configuration still matches the actual hardware.

This always uses hardware timer 3, which should not be used colxfire by application code. From Wikipedia, the free encyclopedia.

Freescale MC3 Board Support. Timers 0 and 1 are never used by eCos so application code is free to manipulate these as required.

These options need to take into account the processor clock speed, a characteristic of the platform rather than the coldtire. In turn the pin settings are used to determine defaults for other hardware settings, for example which of the two on-chip uarts are usable.

The MCF has a small instruction cache of bytes. The ColdFire instruction set is “assembly source” compatible cldfire means of translation software available from the vendor and not entirely object code compatible with the InFreescale also launched Kinetis, an ARM -based product line, leading some industry observers [18] to speculate about the future of the ColdFire range, given that Freescale would have several competing CPU ranges.

Common manufacturer s NXP Semiconductors. This controls the support for gprof-based profiling. If gprof-based profiling is in use then that will use hardware timer 2. It should be colrfire in conjunction with similar sections from the architectural and variant HAL documentation. By default it is active and enabled if the configuration contains mcf527 gprof profiling package, otherwise inactive.

Modified Motorola family. Priority 7 corresponds to non-maskable interrupts and must be used with care: It corresponds directly to the M68K exception number. The relevant code uses hardware timer 2, so that timer is no longer available for application code. There is no data cache.

Archived from the original on The default behaviour is to put the processor to sleep until the next interrupt. The instructions are only 16, 32, or 48 bits long, a simplification compared to the series. It should never be necessary to load this package explicitly.

It should be noted that the Freescale documentation is occasionally confusing when it comes to numbering devices.

NXP ColdFire

The mask and unmask operations are straightforward, simply manipulating the on-chip interrupt controller. This is fully supported by the processor HAL.

Usually the processor made to sleep, halting the cpu but leaving all peripherals active. Coodfire was formerly manufactured by Freescale Semiconductor formerly the semiconductor division of Motorola which merged with NXP in This page was last edited on 15 Septemberat
