TDLAR is a 32-bit readable/writable register that specifies the start address of the transmit
descriptor list. Descriptors have a boundary configuration in accordance with the descriptor length
indicated by the DL bit in EDMR. This register must not be written to during transmission.
Modifications to this register should only be made while transmission is disabled by the TR bit
(= 0) in the E-DMAC transmit request register (EDTRR).

If the receive function is disabled during frame reception, write-back is not performed
successfully to the receive descriptor. Following pointers to read a receive descriptor
become abnormal and the E-DMAC can not operate successfully. In this case, to make
the E-DMAC reception enabled again, execute a software reset by the SWR bit in
EDMR0 (EDMR1). To make the E-DMAC reception disabled without executing a
software reset, specify the RE bit in ECMR0 (ECMR1). Next, after the E_DMAC has
completed the reception and write-back to the receive descriptor has been confirmed,
disable the receive function of this register.
