These reside in mcu-module .rodata, are uploaded to MCU register 0x05 and are usually size 0x4003 bytes. (0x4000 bytes with 3 byte magic?)

There exists an alternate code path where uploading is done using register 0x3B (decided by making some nonsense conclusions about registers 0x0F and 0x10). This may be a "hack" around early versions of MCU? Register 0x3B is RTC-related on recent versions of MCU, and the "nonsense" condition is not met even on factory MCU firmware.
