This is used by the vendor's flashing tool. It's ROM image + option
ROM image appended (256 bytes).
Option ROM contains some flags and configuration data for the MCU.
Things like oscillator configuration, HW reset pin enable, data EEPROM
enable, etc.

Revert "firmware: Make interrupt signal shorter (10us)"
...
The longer duration is actually required, likely due to debouncing
applied on the SoC side. Even 50us was unreliable.
