Description
The number of packets loaded into the current transmit buffer by the
driver. Value is counted by driver. This value is written into MB86967
register BMPR10<6:0> at the time transmitter is started.
A running count of the number of packets transferred from system
memory to the transmit buffer since entering the Transmit Packet
Write Routine. This parameter can share the same memory location
with RX CNT, because both are not used concurrently in the same
subroutine.
When transmitter finishes transmitting, MB86967 sets this bit high.
Normally cleared by driver prior to starting transmitter. Hardware
reset or DLC EN being set high also clears this bit.
The maximum number of packets that may be processed in the
Transmit Packet Write Routine before passing control to Receive
Packet Read Routine. This parameter can be fixed or allowed to vary
according to need. Typical range for this parameter is 15-32.
When set high, activates transmitter to transmit all packets in the
current transmit buffer. See also TPKT CNT.
Current status of the transmitter, maintained by driver.

Value Description
Transmitter has not finished transmitting packets
previously given to it to transmit.
Transmitter has finished transmitting all packets in its
buffer.
