NAME AND DESCRIPTION
Receive Japanese CRC6 Enable.
0 = use ANSI/AT&T/ITU CRC6 calculation (normal operation)
1 = use Japanese standard JT–G704 CRC6 calculation
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 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 than half a frame, the command will be executed and the 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 14.3 for details.
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. No
action will be taken if the pointer separation is already greater or equal to half a frame.
If pointer separation is less than half a frame, the command will be executed and the
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 14.3 for details.
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.
Receive Channel Monitor Bit 3.
Receive Channel Monitor Bit 2.
Receive Channel Monitor Bit 1.
Receive Channel Monitor Bit 0. LSB of the channel decode.
