you must fill the table below with group of MIOs which are connected to a specific components or peripherals, you do not have to specify pins in B2B, Just mention which B2B is connected to MIOs. The rest is clear in the Schematic.
Example:
| MIO Pin | Connected to | B2B | Notes |
|---|
| MIO12...14 | SPI_CS , SPI_DQ0... SPI_DQ3 SPI_SCK | J2 | QSPI |
