, the dummy bytes
(command code and the number of bytes), and the data bytes. This sequence is illustrated in the following

2-line serial interface configuration command bitmap
The 2-line serial command bytes are used to control the output clock pairs (Y[0:9], Y[0:9]). The output clock pairs
are enabled after power up. During normal operation, the clock pairs can be disabled (set Hi-Z) or enabled
(running) by writing the corresponding bit to the data bytes in the following tables:
Byte 0: Enable/Disable Register
(H = Enable, L = Disable)
Byte 1: Enable/Disable Register
(H = Enable, L = Disable)
