not available to bank 1/2/3 peripherals.
### Proposal
+TODO: REWORK BASED ON GPIO JTAG DIAGRAMS BELOW
The proposed JTAG BS chain is as follows:
* Between each peripheral and GPIO block, add a JTAG BS chain. For example
beast. If there are suggestions to simplify or reduce some of the signals,
that will be helpful.*
-The diagrams below show 1-bit GPIO connectivity, as well as the N-bit case.
+The diagrams below show 1-bit GPIO connectivity, as well as the 4-bit case.
