There are 2 type transport mode (SCLK synchronization mode and start-stop synchronization
mode). When using start
stop synchronization mode, pull the SDATAOUT pin down with about
3.3k
. When using SCLK synchronization mode, pull the SDATAOUT pin up with about 3.3k
. It
is not possible to change the transport mode during working.
Use even parity from FM1 through DataN.
