These bits display the aggregate count of all the POS packets and ATM cells that are dropped
by the TXSDQ due to FIFO overflows. This register is latched when register 0000H is written
to for a global performance monitor update. After the count is latched into the register, the
internal counter is reset to 0 and starts counting again. When this counter reaches its
maximum count, it rolls over.
