3.2 Serial Interface
The serial interface is provided for serial boot and serial API. Since this interface does not control flow with
hardware, you need to control the flow with firmware such as a driver. The firmware dedicated to the internal
controller uses ASCII mode.
3.2.1 Serial Interface Receive Operations
The serial interface supports the following receive data formats:

FM2

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.
In SCLK synchronization mode, data is taken on raising edge of SCLK.
In start
stop synchronization mode, data is taken according to 9600bps with reference to the
StartBit falling edge of the SDATAIN signal regardless of SCLK.
Use even parity from FM1 through DataN. After the parity bit, 1 is needed as StopBit. However,
if 0 is received at this point, it is recognized as a break signal and invalidates receive data.
