The MCI of the 23xx/24xx series used sd-bus and is therefore not an spi port.
Depending on the speed you want from the spi you could use an software spi.

I plan to use both the SSP/SPI ports in TI mode withe Frame pulses. In addition
to this, I need to interface SPI flash memory. I could use LPC 1778, but was
wondering if it is possible to stay with my existing 23xx design.

You can have several peripherals on the same SPI bus. They all should
have chip selects.

Hello,
Both the SPI interfaces of LPC23xx are used up in my design. Is it
possible to use SD/MMC interface to connect simple SPI Flash ?
