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 will force the receive elastic store’s write/read pointers to
a minim separation of half a frame. If pointer separation is
already greater than half a frame, setting this bit will have no
effect. 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 will force the transmit elastic store’s write/read pointers
to a minimum separation of half a frame. If pointer
separation is already greater than half a frame, setting this bit
will have no effect. 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.
