    eQEP:
    The enhanced QEP peripheral uses a 32-bit position counter, supports low-speed
    measurement using capture unit and high-speed measurement using a 32-bit unit timer.
    This peripheral has a watchdog timer to detect motor stall and input error detection logic
    to identify simultaneous edge transition in QEP signals.
    The ADC block is a 12-bit converter, single ended, 16-channels. It contains two
    sample-and-hold units for simultaneous sampling.
    ADC:
    The 280x devices support the following serial communication peripherals:
    eCAN:
    This is the enhanced version of the CAN peripheral. It supports 32 mailboxes, time
    stamping of messages, and is CAN 2.0B-compliant.
    The SPI is a high-speed, synchronous serial I/O port that allows a serial bit stream of
    programmed length (one to sixteen bits) to be shifted into and out of the device at a
    programmable bit-transfer rate. Normally, the SPI is used for communications between the
    DSP controller and external peripherals or another processor. Typical applications include
    external I/O or peripheral expansion through devices such as shift registers, display
    drivers, and ADCs. Multi-device communications are supported by the master/slave
    operation of the SPI. On the 280x, the SPI contains a 16-level receive and transmit FIFO
    for reducing interrupt servicing overhead.
    The serial communications interface is a two-wire asynchronous serial port, commonly
    known as UART. On the 280x, the SCI contains a 16-level receive and transmit FIFO for
    reducing interrupt servicing overhead.
    The inter-integrated circuit (I
    2
    C) module provides an interface between a DSP and other
    devices compliant with Philips Semiconductors Inter-IC bus (I
    2
    C-bus) specification version
    2.1 and connected by way of an I
    2
    C-bus. External components attached to this 2-wire
    serial bus can transmit/receive up to 8-bit data to/from the DSP through the I
    2
    C module.
    On the 280x, the I
    2
    C contains a 16-level receive and transmit FIFO for reducing interrupt
    servicing overhead.

    The 280x devices contain three peripheral register spaces. The spaces are categorized as follows:
    Peripheral
    Frame 0:
    Peripheral
    Frame 1
    Peripheral
    Frame 2:
    These are peripherals that are mapped directly to the CPU memory bus.
    See
    Table 3-6
    These are peripherals that are mapped to the 32-bit peripheral bus.
    See
    Table 3-7
    These are peripherals that are mapped to the 16-bit peripheral bus.
