SERIAL CONFIGURATION MAP

The serial bits will be read by the clock buffer 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 2 – Bits 7, 6, 5, 4, 3, 2, 1, 0

All unused register bits (Reserved and N/A) should be desined as “Don’t Care”. It is expected that the controller will force all of these bits to a

“0” level.

All register bits labeled “Initialize to 0” must be written to zero during intialization. Failure to do so may result in a higher than normal operating

current. The controller will read back the last written value.

Byte 0:

Active/inactive register

1 = enable; 0 = disable
