==== Bootloader TWI memory Requirements
The bootloader can access an TWI-compatible memory via the processor's top entity TWI port. Single- and dual address memory is supported, and reading is done in the following pattern
`Slave Address + Enabled Read | Memory Address Byte 0 | Memory Address 1 (optional) | Read Byte 0 | Read Byte 1 | Read Byte 2 | Read Byte 3`.
`Device Address + Enabled Read | Memory Address Byte 0 | Memory Address 1 (optional) | Read Byte 0 | Read Byte 1 | Read Byte 2 | Read Byte 3`.
The addresses are incremented until the end of the program binary is reached.
A python upload script for uploading is provided in the `sw/eeprom_upload` folder. Currently only for the https://www.robot-electronics.co.uk/htm/usb_iss_tech.htm[USB-ISS] module.
