To setup the â??bit synchronous modeâ?, one example can be a reference as shown on the AP1 or AP2 module document â??ANTAP1MxIB RF Transceiver Moduleâ? or â??AP2 RF Transceiver Moduleâ?, which can be downloading from

In the document, the â??Pin Assignmentâ? table describes more detail about the PIN definitions. For example,if set toâ??bit sync modeâ?, the DIP switches can be set as: DIP-2: PORTSEL=1 (tie to VCC), DIP-3: SFLOW =1 (tie to VCC).
The schematic also shows how many pins are required:
PIN3:SIN/RXD
PIN4:SOUT/TXD
PIN5:RTS/SEN
PIN9:SUSPEND/SRDY
PIN10:SMSGRDY/SLEEP
PIN19:BR2/SCLK
To implement the above pin definition, the rest switches on the battery board are tie to "VCC" as well.
How to connect the pin-outs to the different MCU is indeed userâ??s host controller independently. The principle is quite similar as this example.
