Detailed Description

HW_ENET_TDSR - Transmit Buffer Descriptor Ring Start Register (RW)

Reset value: 0x00000000U

TDSR provides a pointer to the beginning of the circular transmit buffer descriptor queue in external memory. This pointer must be 64-bit aligned (bits 2-0 must be zero); however, it is recommended to be 128-bit aligned, that is, evenly divisible by 16. This register must be initialized prior to operation.
