I/O registers are composed of the input path for handling data from the pin to the
core, the output path for handling data from the core to the pin, and the output enable
path for handling the OE signal to the output buffer. These registers allow faster
source-synchronous register-to-register transfers and resynchronization. You can
bypass each block of the output and output enable paths.
