Tool/software:
TICS Pro version 1.7.9.0 is outputting an incorrect R number for the final re-lock of the EEPROM in the "Export EEPROM Instructions" file.
# Lock EEPROM (NVMUNLK)
R180 0x00A400
The register number should be 164 not 180. Thankfully, the full 3 byte address/value sequence has the correct 0x00A4 (164) register number.
