→What do the numbers in the boxes mean?
Connected straight to the Raspberry Pi GPIO pins are in the range 0 - 99 whilst devices using the I2C connection and an MCP23017 start at 100 and go up from there.

In the first case you are specifically identifying the Pi GPIO pins connected to the encoders, in the second you are identifying the pins on the MCP23017 chip that are connected to the encoders and also describing how the I2C bus is connected to the Pi.

This was the original way the pins where connected to the encoders and it is still supported in the Zynthian. The Broadcom Addresses are put into the appropriate box to link the encoder to the zynth.
