Component output signals

Digital outputs of the component are used for connecting programmable blocks with output lines RO. Signal could be routed from output lines further toward output of the microcontroller or input of some other component. Output multiplexers are used for connecting lines of programmable blocks with global output lines.

Multiplexer

Depending on the state of multiplexer, output (RO) or input (RI) line of programmable block could be connected.

Logic circuit

Selected signal can be brought to the output of logic circuit. As other input could be used some of adjacent lines of programmable blocks (RO). Logic circuit can:

·         pass one of two signals

·         invert input signals

·         do logic operations AND, OR or XOR over input signals which could be inverted previously.
