The message length (LENGTH16) bit selects the length of the tail trace message to be
transmitted. When LENGTH16 is set to logic 1, the length of the tail trace message is 16
bytes. When LENGTH16 is set to logic 0, the length of the tail trace message is 64 bytes.
The single byte message enable (BYTEEN) bit enables the single byte tail trace message.
When BYTEEN is set to logic 1, the length of the tail trace message is 1 byte. When
BYTEEN is set to logic 0, the length of the tail trace message is determined by LENGTH16.
BYTEEN has precedence over LENGTH16.
The all zero message enable (ZEROEN) bit enables the transmission of an all zero tail trace
message. When ZEROEN is set to logic 1, an all zero message is transmitted. When
ZEROEN is set to logic 0, the RAM message is transmitted. The enabling and disabling of
the all zero tail trace message is not done on message boundary since the receiver is required
to perform filtering on the message.
