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
Reserved and unused bits should be programmed to “0”
SMBus Address for the CY28354 is as follows.
