Lab 2: Define how SW needs to be adapted to enable GPIO shift register functionality #1

Closed andreaskurth closed 1 year ago

andreaskurth commented 1 year ago

In the current draft PR (https://github.com/lowRISC/ibex-demo-system/pull/11), SW always accesses the GPIO shift register. This would not work with the GPIO module prior to the modification in the last task of Lab 2. We therefore need to have a switch in SW (see https://github.com/lowRISC/ibex-demo-system/pull/11#discussion_r1054604568) and update the instructions of Lab 2 to flip this switch (see TODO near the end).
