Function
The read value of this bit is always 0.
Not affected
Starts transmitting packet.
When the transmitter buffer is in the single buffer mode, set
this bit after transferring the transmit packet from the host to
the transmit buffer. When the transmitter buffer is in the dual
buffer mode, set this bit after transferring the transmit packet
to the transmitter buffer and completing transmission of the
packet to the second bank (after the TMT OK bit of DLCR0 is
set).
These bits are decremented each time transmission of one
packet is completed, and display the count of packets that
have not been transmitted yet. They are set to 00H after all
packets have been transmitted.
The MB86967 can start transmitting more than one packet
using one transmit command. Set the TMST bit and write the
transmit packet count (the count of packet transferred to buffer
memory).
