This Reset-upon-Read register, along with PMON Transmit Valid Cell Count -
MSB contains the 16 bit value for the total number of Valid cells that have
been trnasmitted by the Transmit Cell Processor, since the last read of this
register. This register contains the “Low” byte value of this 16-bit expression.
NOTE: This register is only active if the XRT72L71 has been configured to
operate in the “ATM UNI” Mode.

If the Bi-directional data bus (of the Microprocessor Interface) is configured
to be “8-bits” wide; then this register holds the companion byte of any 16-bit
PMON Count registers, 1-sec Accumulator registers, or the Test Cell Error
Accumulator register, when one of these registers are read, during the previ-
ous Bus cycle.
