FREESCALE HDLC DRIVER

First, new features, such as a DRAM controller and breakpoint logic, have been added. Other channels can work with their own set of pins, allowing possibilities like an Ethernet to T1 bridge, etc. 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.

Freescale Semiconductor products are not designed, intended, or authorized for use as components in freecsale intended for surgical implant into the body, or other applications intended to support or sustain life, or for any other application in which bdlc failure of the Freescale Semiconductor product could create a situation where personal injury or death may occur.

From a logic standpoint, however, a glueless system is maintained. There are no express or implied copyright licenses granted hereunder to design or fabricate any integrated circuits or integrated circuits based on the information in this document.

Although the QUICC is always a bit device internally, it may be configured to operate with a bit frescale bus. In a few cases, a bit in a BD status word had to be shifted. Other channels can work with their own set of pins, allowing possibilities like an Ethernet to T1 bridge, etc.

The family was designed using a hardware description languagemaking the parts synthesizable, and amenable to improved fabrication processes, such as die shrinks.

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: The modules of the microcontroller were designed independently and released as new CPUs could be tested.

The instruction set of the CPU32 core is similar to the without bitfield instructions, and with a few instructions unique to the CPU32 core, such as table lookup and interpolate instructions, and a low-power stop mode. Freescale Semiconductor does not convey any license under its patent rights nor the rights of others.

These features allow 16 or bit data to be read or written at an odd address. 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.

The register addresses within that memory map are different. July Learn how and when to remove this template message. Regardless of the choice of the system bus size, dynamic bus sizing is supported. 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.

These documents may be obtained from the Literature Distribution Centers at the addresses listed at the bottom of this page. There are two CPU cores used in the xx family: The following table identifies the packages and operating frequencies available for the MC Freescale Semiconductor reserves the right to make changes without further notice to any products herein. The Freescale xx formerly Motorola xx is a family of compatible microcontrollers that use a Motorola -based CPU core.

Depending on the capacitance on the system bus, external buffers may be required. Independent receive and transmit clocking, routing, and syncs are supported. Many of these submodules have been carried forward into the Coldfire line of processors.

[PATCH 5/5] drivers/net: support hdlc function for QE-UCC

This configuration does require external address mutiplexers, but the QUICC controls the multiplexers. Views Read Edit View history. These features may be divided into three sub-groups: Ndlc, if such code is accessing the MC peripherals, it will require some modification. 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.

First, new features, such as a DRAM controller and breakpoint logic, have been added. The Freescal is an exception, having an M bus on chip. It particularly excels in communications activities. Two TDM buses may be simultaneously supported with the time slot assigner.

Unsourced material may be challenged and fredscale. Bus sizing allows freexcale,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.
