TABLE 115 - SPI-4 EGRESS CONTROL LANE
TIMING REGISTER (REGISTER_OFFSET 0x2B)
and write access. The SPI-4 egress controllane timing register is used to
manually align the phase of the control lane by adding from 0.1 clock cycle to
0.3 clock cycles of delay.
4 egress control output.
SPI-4 egress data clock timing register
(Block_base 0x0800 + Register_offset 0x2C)
TABLE 116 - SPI-4 EGRESS DATA CLOCK TIMING
REGISTER (REGISTER_OFFSET 0x2C)
has read and write access. The SPI-4 egress data clock timing control register
is used to manually align the phase of the SPI-4 egress data clock to the data
and control lanes by adding from 0.1 clock cycle to 0.9 clock cycles of delay to
the data clock. Note that tap selection is not monotonic with the number in bit field
[3:0].
4 egress data clock.
4 egress data lane n.

SPI-4 egress status timing register (Block_base
0x0800 + Register_offset 0x2D)
TABLE 117 - SPI-4 EGRESS STATUS TIMING
REGISTER (REGISTER_OFFSET 0x2D)
0x2D has read and write access. The SPI-4 egress status timing register is used
to manually align the phase of the status lane n by adding from 0.1 clock cycle
to 0.3 clock cycles of delay. The STC0[1:0] and STC1[1:0] fields are valid only
for LVDS status, not for LVTTL status.
4 egress status lane n.

TABLE 118 - SPI-4 EGRESS STATUS CLOCK TIM-
ING REGISTER (REGISTER_OFFSET 0x2E)
Register_offset 0x2E has read and write access. The SPI-4 egress status clock
timing register is used to manually align the phase of the SPI-4 egress status clock
to the status outputs by adding from 0.1 clock cycle to 0.9 clock cycles of delay
to the status clock output. Note that tap selection is not monotonic with the number
in bit field [3:0].
