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 byte 0x1.

Six of the eight Connection Matrix Virtual Inputs are dedicated to this virtual input function. 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).

Two of the eight Connection Matrix Virtual Inputs are shared with Pin digital inputs (GPIO0 Digital or I2C_virtual_0 Input), and

(GPIO1 Digital or I2C_virtual_1 Input). If the virtual input mode is selected, 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). The I2C disable/enable register bit [31] selects whether the Connection Matrix

input comes from the Pin input or from the virtual register:

 Select SCL & Virtual Input 0 or GPIO0

 Select SDA & Virtual Input 1 or GPIO1

See Table 21 for Connection Matrix Virtual Inputs.
