LPC11U68JBD48 - DSR Pin State

I am looking at using the LPC11U68 in a product. I need USART0 and 1 and the SPI (SSP) 0 and 1.

With regards to the USART0, I just need the TX, RX, CTS and RTS.

My question is, should I allocate the DSR0 (PIO1_20) to the SSP1_SCK in the pins function register, what will be the 'state' of DSR0 that the modem control register will see?

Does it see it as permanently ready?


Thanking you in advance
