101 / 154 page ![]() DA16200 Ultra Low Power Wi-Fi SoC Datasheet Revision 3.6 04-Jan-2023 CFR0011-120-00 101 of 153 © 2023 Renesas Electronics Bit Mode Symbol Description Reset 0 = UART RS-485 mode is disabled 1 = UART RS-485 mode is enabled 10.3 I2S Register DA16200 provides an I2S interface that has both I2S transmission and reception functions. However, the transmission and reception functions cannot be used at the same time. The transmit and receive functions can be selected by setting the register. When the I2S clock divider register is used, the internal PLL clock can be variably applied to the I2S clock source. The available I2S clock source is 24/48 MHz. There is also a way to apply the I2S clock source directly from the outside with the use of the GPIO pin.
