C 1:10 clock buffer

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.

NOTE:
1. Inactive means outputs are held LOW and are disabled from switching. These outputs are designed to be configured at power-on and are
not expected to be configured during the normal modes of operation.
