22.4.1.13 Receiver Global Control Register (RGBLCTL)
Alias of the global control register (GBLCTL). Writing to the receiver global control register (RGBLCTL)
affects only the receive bits of GBLCTL (bits 4-0). Reads from RGBLCTL return the value of GBLCTL.
RGBLCTL allows the receiver to be reset independently from the transmitter. The RGBLCTL is shown in
and described in
. See
for a detailed description of GBLCTL.

0
Reserved. The reserved bit location always returns the default value. A value written to this field has no
effect. If writing to this field, always write the default value for future device compatibility.
12
XFRST
x
Transmit frame sync generator reset enable bit. A read of this bit returns the XFRST bit value of
GBLCTL. Writes have no effect.
11
XSMRST
x
Transmit state machine reset enable bit. A read of this bit returns the XSMRST bit value of GBLCTL.
Writes have no effect.
10
XSRCLR
x
Transmit serializer clear enable bit. A read of this bit returns the XSRCLR bit value of GBLCTL. Writes
have no effect.
9
XHCLKRST
x
Transmit high-frequency clock divider reset enable bit. A read of this bit returns the XHCLKRST bit
value of GBLCTL. Writes have no effect.
8
XCLKRST
x
Transmit clock divider reset enable bit. A read of this bit returns the XCLKRST bit value of GBLCTL.
Writes have no effect.
