Value
SERDES A Global Control Register (Acts on Channels A, B, C, and D)

—
GPRBS_A
Global Enable.
The GPRBS bit
globally enables
the PRBS gen-
erators and
checkers all
four channels of
SERDES A
when GPRBS =
1. GPRBS = 0
on device reset.
GMASK_A
Global Mask.
The GMASK
globally masks
all the channel
alarms of SER-
DES A when
GMASK = 1.
This prevents
all the transmit
and receive
alarms from
generating an
interrupt.
GMASK = 1 on
device reset.
GSWRST_A
RESET Func-
tion. The
GSWRST bit pro-
vides the same
function as the
hardware reset
for the transmit
and receive sec-
tions of all four
channels of
ASERDES A,
except that the
device congura-
tion settings are
not affected when
GSWRST is
asserted.
GSWRST = 0 on
device reset. This
is not a self-clear-
ing bit. Once set,
it must be cleared
by writing a 0 to it.
GPWRDNT_A
Powerdown
Transmit Func-
tion. When
GPWRDNT = 1,
sections of the
transmit hard-
ware for all four
channels of
SERDES A are
powered down
to conserve
power.
GPWRDNT = 0
on device reset.
GPWRDNR_A
Powerdown
Receive Func-
tion. When
GPWRDNR =
1, sections of
the receive
hardware for all
four channels of
SERDES A are
powered down
to conserve
power.
GPWRDNR = 0
on device reset.
GTRISTN_
A
Active-Low
TRISTN
Function.
When
GTRISTN =
0, the
CMOS out-
put buffers
for SER-
DES A are
3-stated.
GTRISTN =
1 on device
reset.
—
GTESTEN_A
Test Enable
Control. When
GTESTEN = 1,
the transmit
and receive
sections of all
four channels
of SERDES A
are placed in
test mode.
GTESTEN = 0
on device
reset.
