USER INFORMATION
The ZiLOG Z02201 data pump can be selected for either
parallel or serial synchronous data transfer under software
control. Figure 2 indicates a block 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 programmable coefficients. The hardware and software
interfaces are presented in the subsequent sections.
