iMx6UL Rx485 Mode

It is not clear to me from datasheet about the polarity of the CTS_B pin when set in RS485 mode? Does switching from full duplex to half duplex or vice versa affects the direction of CTS_B pin?

Hi Prabhat

one can check example on p.3162 i.MX6UL Reference Manual:

Set software flow control (CTS pin is controlled by UCR2[12] ),

from sect.53.15.4 UART Control Register 2 (UARTx_UCR2)

0 The CTS_B pin is high (inactive)
1 The CTS_B pin is low (active)
