The ZiLOG Z02201 data pump can be selected for either parallel or serial
synchronous data transfer under software control.
diagram of the general modem chip interface. The hardware and software
configurations can be customized for a particular modem application. The parallel
interface allows direct access to 7 I/O registers, indirect access to the modem
RAM, and is compatible with the Z8, Z80, Z18X family, and other 8-bit
microprocessors. The serial interface is used for data transfer. Controls and status
information are transferred via the parallel interface. The RAM access capability
allows indirect access to diagnostic data, additional status control, and program-
mable coefficients. The hardware and software interfaces are presented in the
subsequent sections.
