SERDES Global Control Registers (ReadWrite) Acts on all four Channels in SERDES Quad A or SERDES Quad B.
30005 - A
30105 - B
[0]
GPRBS_[A:B]
44
Global PRBS Enable. The GPRBS_[A:B] bit globally enables the PRBS
generators and checkers of all four channels when GPRBS_[A:B] = 1.
GRBS_[A:B] overrides the PRBS_xx bits for the individual channels.
GPRBS_[A:B] = 0 on device reset.
[1]
GMASK_[A:B]
Global Mask. When GMASK_[A:B] = 1, the transmit and receive alarms
of all channel in the SERDES quad are prevented from generating an
interrupt (i.e., they are masked or disabled). The GMASK_[A:B] bit over-
rides the individual MASK_xx bits. GMASK_[A:B] = 1 on device reset.
[2]
GSWRST_[A:B]
Software reset bit. The GSWRST_[A:B] bit provides the same function
as the hardware reset for the transmit and receive sections of all four
channels, except that the device conguration settings are not affected
when GSWRST_[A:B] is asserted. This is not a self-clearing bit. Once
set, this bit must be manually set and cleared. The GSWRST_[A:B] bit
overrides the individual SWRST_xx bits. GSWRST_[A:B] = 0 on device
reset.
[3]
GPWRDNT_[A:B]
Powerdown Transmit Function. When GPWRDNT_[A:B] = 1, sections of
the transmit hardware for all four channels of are powered down to con-
serve power. The GPWRDNT_[A:B] bit overrides the individual
PWRDNT_xx bits.
GPWRDNT_[A:B] = 0 on device reset.
[4]
GPWRDNR_[A:B]
Powerdown Receive Function. When GPWRDNR_[A:B] = 1, sections of
the receive hardware for all four channels are powered down to conserve
power. The GPWRDNR_[A:B] bit overrides the individual PWRDNR_xx
bits.
GPWRDNR_[A:B] = 0 on device reset.

Reserved, 1 on device reset.

[7]
GTESTEN_[A:B]
Test Enable Control. When GTESTEN_[A:B] = 1, the transmit and
receive sections of all four channels are placed in test mode. The
GTESTEN_[A:B] bit overrides the individual TESTEN_xx bits.
GTESTEN_[A:B] = 0 on device reset.
