In , Freescale 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. It should be read in conjunction with similar sections from the architectural and variant HAL documentation. Unloading the package should only happen as a side effect of switching target hardware. By default it is active and enabled if the configuration contains the gprof profiling package, otherwise inactive. If gprof-based profiling is in use then that will use hardware timer 2.

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. It corresponds directly to the M68K exception number. Unloading the package should only happen as a side effect of switching target hardware. This always uses hardware timer 3, which should not be used directly by application code.
If gprof-based profiling is in use then that will use hardware timer 2. This is fully supported by the processor HAL.
NXP ColdFire – Wikipedia
The default behaviour is to put the processor to sleep until the next interrupt. 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 Modified Motorola family.
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. This controls the support for gprof-based profiling.
It was formerly manufactured by Freescale Semiconductor formerly the semiconductor division of Motorola codlfire merged with NXP in 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. Common manufacturer s NXP Semiconductors.
Timers 0 and 1 are never used by eCos so application code is free to manipulate these as required. Freescale MC3 Board Support.
Also, floating point intermediates are 64 bits and not 80 bits as in the and coprocessors. However, Fido has its own unique architecture and shares the instruction set with 68k only.
Usually the processor made to sleep, halting the cpu but leaving all peripherals active. This uses hardware timer 2, so application code should not manipulate this timer if profiling is enabled. It should be read in conjunction with similar sections from the architectural and variant HAL documentation. The MCF has a small instruction cache of bytes.
Retrieved from ” https: The relevant code uses hardware timer 2, so that timer is no longer available for application coldfird. The instructions are only 16, 32, or 48 bits long, a coldvire compared to the series. Priority 7 corresponds to non-maskable interrupts and must be used with care: If the timer is required but a platform HAL provides an alternative implementation of the profiling support then this option can be disabled. There is no data cache.
