Data Path
Both the transmitter and the receiver in the channel are actually microcoded serial proces-
sors. As the data shifts through the transmit or receive shift register, the microcode
watches for specific bit patterns, counts bits, and at the appropriate time transfers data to
or from the FIFOs. The microcode also checks status and generates status interrupts as
appropriate.
