external microprocessor. The external microprocessor sends commands
to configure the device and read feedbacks. The downloaded software
interprets these commands and the embedded controller executes
these commands. This relieves programmers from accessing vast regis-
ters. Just by accessing a few registers, programmers can use a set of
well-defined commands to communicate with IDT82V2608.

plexed Motorola microprocessor interfaces. For Intel microprocessor
interface, the MPM pin should be connected to VDD; for Motorola micro-
processor interface, the MPM pin should be connected to ground.

commands and data from the external microprocessor; the other is
Output FIFO, which is used to send data to the external microprocessor.
The lengths of these two FIFOs are both 16 bytes. These two FIFOs can
only be accessed through registers.
