PRELIMINARY
6.3 CONNECTION MATRIX VIRTUAL INPUTS
As mentioned previously, the Connection Matrix inputs come from the outputs of various digital macrocells on the
device. Eight of the Connection Matrix inputs have the special characteristic that the state of these signal lines comes
from a corresponding data bit written as a register value via I2C. This gives the user the ability to write data via the
serial channel, and have this information translated into signals that can be driven into the Connection Matrix and
from the Connection Matrix to the digital inputs of other macrocells on the device. The I2C address for reading and
writing these register values is at 0x7A (0122).
An I2C write command to these register bits will set the signal values going into the Connection Matrix to the desired
state. A read command to these register bits will read either the original data values coming from the NVM memory
bits (that were loaded during the initial device startup), or the values from a previous write command (if that has
happened). See Table 21.
