These notes should be in modem data sheet not here>>>>>>>>>>>>>>>>>>>>
When designing the modem into a custom board, care must be taken to be sure the modem comes out of reset
properly. Under normal circumstances these aren’t needed, but if these signals have signal traces connected to
them, additional pull-ups should be added.

~FSYNC - pin 24 – 10K resistor to VCC
SDO
DIGITAL SERIAL INTERFACE
are digital CMOS versions of the RS-232 interface signals. The voltage level is set by the voltage selection on the
evaluation board or module installed.
PARALLEL INTERFACE
The parallel interface consists of an 8 bit bi-directional data bus, bus contols plus 5 volt power and ground.
Make voltage selector either 5 v or 3.3v, user selectable. This voltage should be the one on the parallel
interaface connector.
See the module datasheet for details of the user interface signals
The serial interface consists of serial receive and transmit data, flow control signals plus power and ground. These
- pin 33 – must be held high during reset (a 10K resistor or directly pulled to VCC)
- pin 40 – 10K resistor to VCC
- pin 27 – 10K resistor to VCC
