Hi Guys, Is their a way of creating a 24bit GPIO Port on the LPC4337 ?

I've mapped out the Ports on the LPC4337 and their is no Ports that have 24bits. The largest Port is PORT 1 with 21bits.
My project needs 24bits and I would like to write a 24bit value to one port which equals 1 machine cycle.

Is their a way to create a 24bit port by joining 2 ports together or am I limited to a maximum of 21bits on the LPC4337.

PORT 0 = 2 Bits
PORT 1 = 21 Bits
PORT 2 = 14 Bits
PORT 3 = 9 Bits
PORT 4 = 11 Bits
PORT 5 = 8 Bits
PORT 6 = 13 Bits
PORT 7 = 8 Bits

Thanks Guys for your help on this one.

Pete :)
