First, new features, such as a DRAM controller and breakpoint logic, have been added. It will also execute the entire M instruction set. Freescale Semiconductor does not convey any license under its patent rights nor the rights of others. This configuration does require external address mutiplexers, but the QUICC controls the multiplexers. There are two CPU cores used in the xx family: It also offers parity support for the DRAM. Freescale Semiconductor reserves the right to make changes without further notice to any products herein.

The family was designed using a hardware description languagemaking the hslc synthesizable, and amenable to improved fabrication processes, such as die shrinks. The IMB provides a common interface for all modules of the M family, which allows Freescale to develop new devices more quickly by using the library of existing modules.
Each module utilizes the bit IMB. Freescale Semiconductor makes no warranty, representation or guarantee regarding the suitability of its products for any particular purpose, nor does Freescale Semiconductor assume any liability arising out of the application or use of any product or circuit, and specifically disclaims any and all liability, including without limitation consequential or incidental damages.
However, if such code is accessing the MC peripherals, it will require some modification. In a few cases, a bit in a BD status word had to be shifted.
[PATCH 5/5] drivers/net: support hdlc function for QE-UCC
The MC is an exception, having an M bus on chip. The QUICC keeps the best features of the MC, while making the changes required to provide for the increased flexibility, integration, and performance requested by customers. Bus sizing allows 8-,and bit peripherals and memory to exist in the bit system bus mode and 8- and bit peripherals and memory to exist in the bit system bus mode. The term “quad” comes from the fact that there are four serial communications controllers SCCs on the device; however, there are actually seven serial channels: Third, new configurations, such as slave mode and internal hdlv by an external master, are supported.
Many of these submodules have been carried forward into the Coldfire line of processors.

However, they offer some minor enhancements, such as the internal cascading of two timers to form a bit timer. From Wikipedia, the free encyclopedia. Views Read Edit View history. The following table identifies the packages and operating frequencies available for the MC Freescale Semiconductor does not convey any license under its patent rights nor the rights of others.
Although the QUICC is always a bit device internally, it may be configured to operate with a bit data bus. The Freescale xx formerly Motorola xx is a family of compatible microcontrollers that use a Motorola -based CPU core.

These features may be divided into three sub-groups: The register addresses within that memory map are different. The following paragraphs briefly discuss this endeavor in terms of architectural approach, hardware issues, and software issues. July Learn how and when to remove this template message.
