W305B Serial Configuration Map

The serial bits will be read by the clock driver in the following

order:

Byte 0 – Bits 7, 6, 5, 4, 3, 2, 1, 0

Byte 1 – Bits 7, 6, 5, 4, 3, 2, 1, 0

Byte N – Bits 7, 6, 5, 4, 3, 2, 1, 0

All unused register bits (reserved and N/A) should be written

to a “0” level.

All register bits labeled “Initialize to 0” must be written to zero

during initialization.
