Documentation says:
The SC16IS740/750/760 is a slave IÂC-bus/SPI interface to a single-channel
high performance UART.
...
The SC16IS740/750/760 also provides additional advanced features such
as auto hardware and software flow control, automatic RS-485 support...
So why do you position this chip as RS485 only? Automatic direction for
RS485 is just a feature as an addition for standart UART.
