NAME AND DESCRIPTION
RJC
CCR6.7
Receive Japanese CRC6 Enable.
0 = use ANSI/AT&T/ITU CRC6 calculation (normal
operation)
1 = use Japanese standard JT–G704 CRC6 calculation
RESALGN
CCR6.6
Receive Elastic Store Align. Setting this bit from a zero to a
one may force the receive elastic store’s write/read pointers
to a minimum separation of half a frame. No action will be
taken if the pointer separation is already greater or equal to
half a frame. If pointer separation is less then half a frame,
the command will be executed and data will be disrupted.
Should be toggled after RSYSCLK has been applied and is
stable. Must be cleared and set again for a subsequent align.
See Section 17 for details.
TESALGN
CCR6.5
Transmit Elastic Store Align. Setting this bit from a zero to
a one may force the transmit elastic store’s write/read
pointers to a minimum separation of half a frame. No action
will be taken if the pointer separation is already greater or
equal to half a frame. If pointer separation is less then half a
frame, the command will be executed and data will be
disrupted. Should be toggled after TSYSCLK has been
applied and is stable. Must be cleared and set again for a
subsequent align. See Section 17 for details.
RCM4
CCR6.4
Receive Channel Monitor Bit 4. MSB of a channel decode
that determines which receive channel data will appear in the
RDS0M register. See Section 13 for details.
RCM3
CCR6.3
Receive Channel Monitor Bit 3.
RCM2
CCR6.2
Receive Channel Monitor Bit 2.
RCM1
CCR6.1
Receive Channel Monitor Bit 1.
RCM0
CCR6.0
Receive Channel Monitor Bit 0. LSB of the channel
decode.
