This register can be read when the RPAGE bit in the GRWCR register is 1.
• TID [7:0] Bits
These bits indicate the label information of transmit history data stored in the transmit history buffer.
• BN[1:0] Bits
These bits indicate the transmit source buffer number of transmit history data stored in the transmit history
buffer.
• BT[1:0] Bits
These bits indicate the transmit source buffer type of transmit history data stored in the transmit history buffer.
