Input clock phase adjust, Bits[2:0]
(Value is number of input clock
cycles of phase delay)
000 = no delay
001 = 1 input clock cycle
010 = 2 input clock cycles
011 = 3 input clock cycles
100 = 4 input clock cycles
101 = 5 input clock cycles
110 = 6 input clock cycles
111 = 7 input clock cycles
0x00
On devices that use
global clock divide,
determines which
phase of the divider
output is used to
supply the output
clock; internal
latching is
unaffected.
