The iMX53 reference manual mentions several times that RTS is an input, and CTS is an output. However, Table 76-1 on page 4627 shows RTS and CTS changing to input or output based on the DCEDTE bit. Could someone explain?

The datasheet relates to the UART + additional signal multiplexing between the UART peripheral and the IC pad, while the Reference Manual describes only the peripheral boundary
