–
CCR5.7
Not Assigned. Should be set to zero when written
RESALGN
CCR5.6
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
CCR5.5
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
CCR5.4
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
CCR5.3
Receive Channel Monitor Bit 3.
RCM2
CCR5.2
Receive Channel Monitor Bit 2.
RCM1
CCR5.1
Receive Channel Monitor Bit 1.
RCM0
CCR5.0
Receive Channel Monitor Bit 0. LSB of the channel decode.
