Sideband Interface
Table B–17 describes the application-side sideband signals.
Table B–17. Sideband Signals
Signal Bit Description
app_int_sts_icm
— Same as
app_int_sts
on the IP core interface. ICM delays this signal by one clock. (3)
cfg_busdev_icm
— Delayed version of
cfg_busdev
on the IP core interface. (2)
cfg_devcsr_icm
— Delayed version of
cfg_devcsr
on the IP core interface. (2)
cfg_linkcsr_icm
—
Delayed version of
cfg_linkcsr
on IP core interface. ICM delays this signal by one
clock. (2)
cfg_tcvcmap_icm
— Delayed version of
cfg_tcvcmap
on IP core interface. (2)
cpl_err_icm
— Same as
cpl_err_icm
on IP core interface (1). ICM delays this signal by one clock.
pex_msi_num_icm
— Same as
pex_msi_num
on IP core interface (3). ICM delays this signal by one clock.
cpl_pending_icm
— Same as
cpl_pending
on IP core interface (1). ICM delays this signal by one clock.
app_int_sts_ack_ic
m
—
Delayed version of
app_int_sts_ack
on IP core interface. ICM delays this by one
clock. This signal applies to the ×1 and ×4 IP cores only. In ×8, this signal is tied low.
cfg_msicsr_icm
—
Delayed version of
cfg_msicsr
on the IP core interface. ICM delays this signal by one
clock.
test_out_icm
[8:0]
This is a subset of
test_out
signals from the IP core. Refer to Appendix B for a
description of
test_out
.
[4:0]
“ltssm_r” debug signal. Delayed version of
test_out[4:0]
on ×8 IP core interface.
Delayed version of
test_out[324:320]
on ×4/ ×1 IP core interface.
[8:5]
“lane_act” debug signal. Delayed version of
test_out[91:88]
on ×8 IP core interface.
Delayed version of
test_out[411:408]
on ×4/ ×1 IP core interface.
