Register Read and Write commands contain only 5 address bits. But the internal address bus of the CS5464 is
12 bits wide. Therefore, registers are organized into “Pages”. There are 128 pages of 32 registers each. The
Page register provides the 7 high-order address bits and selects one of the 128 register pages. Not all pages
are used,
Page is a write-only integer containing 7 bits.
Default = 1 (K=1)

Phase compensation for channel 1. Sets a delay in voltage, relative to current. Phase is signed
Allows the E1 and E2 pins to be configured as open-drain outputs.
