INTERFACES
identifier. Interrupts due to TIM status change are masked when TIME is set
low.
TIMV:
The TIUV bit indicates the trail trace identifier mismatch status of tributary
TU #1 in TUG2 #1 or TU3.
LEN16:
The path trace message length bit (LEN16) selects the length of the path
trace message to be 16 bytes or 64 bytes for tributary TU #1 in TUG2 #1 or
TU3. When LEN16 is set high, the message length is set to 16 bytes. When
LEN16 is set low, the message length is set to 64 bytes.
NOSYNC:
The path trace message synchronization disable bit (NOSYNC) disables the
synchronized writing of the path trace message into the trace buffer based on
the contents of the message for tributary TU #1 in TUG2 #1 or TU3. When
LEN16 is set high and NOSYNC is set low, the receive path trace message
byte with its most significant bit set to logic one will be written to the first
location in the buffer. When LEN16 is set low, and NOSYNC is also set low,
the byte after the carriage return/linefeed (CR/LF) sequence will be written to
the first location in the buffer. When NOSYNC is set high, synchronization is
disabled, and the path trace message buffer behaves as a circular buffer.
CONFIG[1:0]:
The CONFIG[1:0] bits specify the tributary configuration of tributary group
TUG2 #1. The CONFIG[1:0] bits have no effect in TU3 mode. The
configuration specified by the CONFIG[1:0] bits are selected as follows:
