Modes of Operation

Standard PCMCIA mode:

This is the standard operating mode of the RPE-1. The card is used as a standard 8-bit PCMCIA I/O device. The host PC automatically configures its internal memory and interrupt mapping based on so called CIS (Configuration Information Structure, specified in PC Card '95 standard ) memory contents stored inside the SMART ASIC within the RPE-1 baseband.

The RPE-1 is controlled through a number of memory mapped registers. The digital audio interface is supported through a dedicated FIFO buffered memory locations.

Vertical (i.e. non-PCMCIA) mode:

For host devices not having a free PCMCIA slot the RPE-1 has been designed to support also direct serial bus operation. In this mode the PCMCIA connector is no longer literally a PCMCIA connector, but a number of connector signals have been redefined to support new logical interfaces.

The typical RPE-1 host interface is RS232C. The application specific socket for the Cellular Card Phone is assumed to contain all 3.3V to RS232C buffering circuitry, a 3.3V max. 1A supply regulator and a system RESET generator. Should also voice calls be required in the application, the related codec and analog amplifying circuitry would become essential as well.

The vertical operating mode is activated by grounding pin 62 (SPKR#/BVD2) in the PCMCIA connector before card RESET is released. Pin 62 (SPKR#/BVD2) must be kept grounded all the time when operating in non-PCMCIA mode.

Technical Documentation System Module

The SPKR#/BVD2 pin has an internal pull-up resistor ensuring standard PCMCIA mode operation if the pin is left unconnected.
