14.5.3.2.11 Transmit Descriptor Base Address Registers (TBASE0–TBASE7)
The TBASEn registers are written by the user with the base address of each TxBD ring n. Each such value
must be divisible by eight, since the three least significant bits always write as 000.

14.5.3.2.12 Transmit Time Stamp Identification Register (TMR_TXTS1–2_ID)
Transmit time stamp identification register (TMR_TXTSn_ID). This register holds the identification
number of the transmitted frame corresponding to the timestamp captured in TMR_TXTSn_H/L. Each
time the eTSEC is instructed to capture the timestamp of an outgoing frame via TxFCB[PTP] the
associated field in TxFCB[PTP_ID] is stored in this register, overwriting the previous value.
This register is read only in normal operation.

BDs to allocate for the transmit packets. The user must initialize TBASE before enabling the eTSEC transmit
function on the associated ring.
