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 13 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 13 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 9 for details.
