CFG, Bit C) is set, there is an interrupt when TxCOL increments from 1FFh to 200h. This interrupt provides the host
with an early warning that the TxCOL counter should be read before it reaches 3FFh and starts over (by interrupting
at 200h, the host has an additional 512 counts before TxCOL actually overflows). The TxCOL counter is cleared
when read.
