DESCRIPTION

TAG1
Tag Field 1
R/W
The TAG1 field can further qualify the isochronous reception
for isochronous Receive PORT1 when the MONTAG bit is set.
2
7
IRPORT1
Isochronous
receive port
1 channel
number
R/W
IR port1 contains the channel number of the isochronous
packets that the receiver accepts. The receiver accepts
isochronous packets with this channel number when the
IRP1EN is set.

9
TAG2
Tag Field 2
R/W
The TAG2 field can further qualify the isochronous reception
for isochronous Receive PORT2 when the MONTAG bit is set.

15
IRPORT2
Isochronous
receive port
2 channel
number
R/W
IR port2 contains the channel number of the isochronous
packets that the receiver accepts. The receiver accepts
isochronous packets with this channel number when the
IRP2EN is set.

ISYNCRCVN
Synchronous
Enable
R/W
In isochronous receive mode to the DM port, when the
ISYNCRCVN enable bits are high, the DMPRE terminal pulses
when an isochronous packet is received whose SYNC bit field
in its header matches the bit pattern in this field. The default is
0000b.
28
IRCVALL
Receive all
isochronous
packets
R/W
When the IRCVALL bit is set high, the TSB12LV32 receives all
isochronous packets regardless of the channel number or tag
number. The default is off.

31
MONTAG
Match on tag
R/W
MONTAG is set when the user wants to only accept
isochronous packets that match both the tag field and the
channel number field. When set, MONTAG indicates that
isochronous receive data is accepted. The default is off.
