8. REGISTER DESCRIPTIONS
In I²C Mode all registers are read/write unless otherwise stated. In SPI mode all registers are write only. All “Re-
served” registers must maintain their default state to ensure proper functional operation. The default state of each
bit after a power-up sequence or reset is indicated by the shaded row in the bit decode table and in the
Quick Reference” on page
Control port mode is entered when the device recognizes a valid chip address input on its I²C/SPI serial control pins
and the EnDevCfg1 and EnDevCfg2 bits are set to 1.
