In addition to setting the clock frequency, the main must also configure the clock polarity and phase with respect to the data. Motorola [4] [5] named these two options as CPOL and CPHA (for clock polarity and clock phase) respectively, a convention most vendors have also adopted. SPI timing diagram for both clock polarities and phases. Data ...
The Motorola floating point support package (FPSP) emulated these instructions in software under interrupt. As this was an exception handler, heavy use of the transcendental functions caused severe performance penalties. Heat was always a problem throughout the 68040's life.
Most SPI master nodes can set the clock polarity (CPOL) and clock phase (CPHA) with respect to the data. This timing diagram shows the clock for both values of CPOL and the values for the two data lines (MISO & MOSI) for each value of CPHA. Note that when CPHA=1, then the data is delayed by one-half clock cycle. SPI operates in the following way:
Die of Motorola 68882. The 68882 is an improved version of the 68881, with better pipelining, and eventually available at higher clock speeds. [3] [4] Its instruction set is exactly the same. Motorola claimed in some marketing literature that it executes some instructions 40% faster than a 68881 at the same clock speed, though this did not ...
An over-the-air update (or OTA update), also known as over-the-air programming (or OTA programming), [1] is an update to an embedded system that is delivered through a wireless network, such as Wi-Fi or a cellular network. [2] [3] [4] These embedded systems include mobile phones, tablets, set-top boxes, cars and telecommunications equipment.
The Motorola 68000 (sometimes shortened to Motorola 68k or m68k and usually pronounced "sixty-eight-thousand") [2] [3] is a 16/32-bit complex instruction set computer (CISC) microprocessor, introduced in 1979 by Motorola Semiconductor Products Sector. The design implements a 32-bit instruction set, with 32-bit registers and a 16-bit internal ...
Another update for the Droid began on August 24, 2010, and it included some minor bug fixes. This update's build number is FRG22D. [31] A third update was released on December 6, 2010, with a version number of 2.2.1 and a build of FRG83D. A fourth update was released on March 9, 2011, with a version number of 2.2.2 and a build of FRG83G. [32]
A Motorola 68EC060 microprocessor. The Motorola 68060 ("sixty-eight-oh-sixty") is a 32-bit microprocessor from Motorola released in April 1994. [4] It is the successor to the Motorola 68040 and is the highest performing member of the 68000 series. Two derivatives were produced, the 68LC060 and the 68EC060.
