1.1 DMA main features ● Four DMA channels shared among several peripherals ● Three transfer directions – Peripheral to memory – Memory to peripheral – Memory to memory ● Hardware and software channel priorities which allow arbitration ● Programmable number of "data to be transferred"...
aPrivateDescriptor: two directions (read and write). • Prepare context buffers process • Add context buffer transmit in Frame context • Transmit private data process • Check the current state of the peripheral • Add context buffer receive in Frame context • Receive private data ...

The chip provides serial-to-parallel and parallel-to-serial converters using an 8-bit wide LVTTL system interface in both receive and transmit directions. The transmit section includes an option to accept a parallel clock signal from the framer/mapper to synchronize the transmit section timing. ...

With power supply applied, the sensor converts any incident magnetic field in the sensitive axis directions to a differential voltage output. The magnetoresistive sensors are of a el-iron (Permalloy) thin-film and patterned as a resistive strip element. In the presence of a magnetic field, a ...
