• Manufacturer Part Number: mlx90313
• Description: Programmable Ir Sensor Interface
• Manufacturer: ETC-unknow

MAINSTM: Reserved
Read access: No
Write access: Directly to internal register in test mode
TEST
Read access: No.
Write access: Directly to internal register.
This register determines the chip mode. It is cleared after POR which corresponds to normal mode.
Writing the proper data in this register will put the chip in test mode which will be indicated with bit ‘Test’
from confreg0.

Read access: No.
The register controls the write access to the eeprom. After POR this register is cleared and the eeprom is
protected, no write access available. Writing the proper data in this register will remove the write
protection of the eeprom and bit EEWREN (bit 1 in Confreg1) will be set.
