Although the QUICC is always a bit device internally, it may be configured to operate with a bit data bus. Other channels can work with their own set of pins, allowing possibilities like an Ethernet to T1 bridge, etc. 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: First, new features, such as a DRAM controller and breakpoint logic, have been added.

[PATCH 5/5] drivers/net: support hdlc function for QE-UCC
This configuration does require external address mutiplexers, but the QUICC controls the multiplexers. 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. Independent receive and transmit clocking, routing, and syncs are supported.

[5/5] drivers/net: support hdlc function for QE-UCC – Patchwork
It particularly excels in communications activities. The modules of the microcontroller were designed independently and released as new CPUs could be tested. The family was designed using a hardware description languagemaking the parts synthesizable, and amenable to improved fabrication processes, such as die shrinks.
It will also execute the entire M instruction set. July Learn how and when to remove this template message. The instruction set of the CPU32 core is similar to the without hdlf instructions, and with a few instructions unique to the CPU32 core, such as table lookup and interpolate instructions, and a low-power stop mode. Although the QUICC is always a bit device internally, it may be configured to operate with a bit data bus.
From Wikipedia, the free encyclopedia. The Freescale xx formerly Motorola xx is a family of compatible microcontrollers that use a Motorola -based CPU core. Should Buyer purchase or use Freescale Semiconductor products for any such unintended or unauthorized application, Buyer shall indemnify and hold Freescale Semiconductor and its officers, employees, subsidiaries, affiliates, and distributors harmless freecale all claims, costs, damages, and expenses, and reasonable attorney fees arising out of, directly or indirectly, any claim of personal injury or death associated with such unintended or unauthorized use, even if such claim alleges that Freescale Semiconductor was negligent regarding the design or manufacture of the part.

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 ffreescale existing modules. Regardless of the choice of the system bus size, dynamic bus sizing is supported. This process let the architects perform “design-ahead” so that when silicon technologies were available, Motorola had designs ready to implement and go to market.
Other channels can work with their own set of pins, allowing possibilities like an Ethernet to T1 bridge, etc. Freescalee, if such code is accessing the MC peripherals, it will require some modification. The MC is an exception, having an M bus on chip.
Articles lacking sources from July All articles lacking sources. Each module utilizes the bit IMB.
Please help improve this article by adding citations to reliable sources. In a few cases, a bit in a BD status word had to be shifted. The following table identifies the packages and operating frequencies available for the MC Depending on the capacitance on the system bus, external buffers may be required.
Third, new configurations, such as freesclae mode and internal accesses by an external master, are supported. Code written for the MC may be adapted in large part.
However, they offer some minor enhancements, such as the internal cascading of two timers to form a bit timer. Two TDM buses may be simultaneously supported with the time slot assigner.
