Tim Edwards	fe1fcbc3a5	Modified the padframe definition to keep the vccd domain continuous around the entire padframe. The vccd1 and vccd2 domains are local to their respective pads, and any bus routing must be done inside the padframe. This means that all pads operate on global vddio for 3.3V as before, but also global vccd for 1.8V. The user 1.8V voltage domain only goes as far as the input to the GPIO control block.	2021-11-03 10:53:09 -04:00
Tim Edwards	332f9ec2e7	Seeding with documentation of pinout and verilog RTL (mostly unchanged from original except to remove blocks that are not supposed to be in this repository like the processor core and the storage).	2021-10-12 16:31:42 -04:00
