C16POA10

C16POA8
C16 Phase Offset Adjustment. These three bits (most significant) in
conjunction with the eight bits of Phase Offset Register 1 allow for
phase shifting of all clocks and frame pulses that are derived from the
C16 clock (C8o, C4o, C2o, F16o, F8o, F0o). The phase offset is an
unsigned number in a range from 0 to 2047. Each increment by one
represents phase-offset advancement by 61.035 ns with respect to
the input reference signal. The phase offset is a two-byte value and it
must be written in one step increments. For example: four writes are
required to advance clocks by 244 ns from its current position of 22H:
write 23H, 24H, 25H, 26H. Writing numbers in reverse order will delay
clocks from their present position.
