1. Share Register Page: This page corresponds to global parameters, such as LMH0324 device ID. This is the
default page at start-up.
2. CableEQ/Drivers Register Page: This page corresponds to IN0 Cable EQ and both OUT0 and OUT1 driver
output settings. Access this page by setting Reg 0xFF[2:0] = 101’b.
