12 REGISTER MAPS AND DESCRIPTIONS
12.1 Registers Bit Maps
Note: In 8-bit mode, register bits[15:8] correspond to the upper byte, and register bits[7:0] correspond to the lower
byte. For example, address 001h is the upper byte (bits [15:8]) and address 000h is the lower byte (bits [7:0]) for
register GL.IDR in 8-bit mode.
All registers listed, including those designated Unused and Reserved, will cause the RDY signal to go low when
written to or read from.
The “—“ designation indicates that the bit is not assigned.
