Reset Value:
This register points to the entry in the transmit buffer queue (descriptor list) currently being used. It is written with the start
location of the transmit buffer descriptor list. The lower order bits increment as buffers are used up and wrap to their original
values after either 1024 buffers or when the wrap bit of the entry is set. This register can only be written when bit TSR.TGO
is low.
As transmit buffer reads can be bursts of two words, it is recommended that bit 2 is always written to zero to prevent a burst
crossing a 1K boundary, in violation of the System Bus specification.
