DSP56F826 Preliminary Technical Data
Transmit Data (TXD0)—transmit data output
SPI Serial Clock—In master mode, this pin serves as an output, clocking
slaved listeners. In slave mode, this pin serves as the data clock input.
After reset, the default state is SCI output.
Transmit Data (TXD1)—transmit data output
SPI Master In/Slave Out—This serial data pin is an input to a master
device and an output from a slave device. The MISO line of a slave device is
placed in the high-impedance state if hte slave device is not selected.
After reset, the default state is SCI output.
Power—These pins provide power to the internal structures of the chip, and
are generally connected to a 2.5V supply.
Analog Power—This pin supplies an analog power source (generally 2.5V).
Power—These pins provide power to the I/O structures of the chip, and are
generally connected to a 3.3V supply.
GND—These pins provide grounding for the internal structures of the chip.
All should be attached to V
Analog Ground—This pin supplies an analog ground.
GND In/Out—These pins provide grounding for the I/O ring on the chip.
All should be attached to V
