5.3 Serial Interface
The S1V3S344 serial interface can be set to clock synchronous, asynchronous (UART), or I2C.
However, only clock synchronous serial transfer can be used for directly accessing the flash memory. Direct
access to the flash memory is not possible with UART or I2C formats.
• Clock synchronous
• Asynchronous (UART)
• I2C
Serial interface selection is defined by the input pin SHISEL[1:0] settings.
Table 5.2 lists serial interface mode settings.
