PIC with 24 pins on the same port

Hi, is there any PIC with 24 bits port that also has 24 outside pins?
I need to control a LCD screen with 24 bit parallel interface.
Right now I'm using a dsPIC33EP512MC204 with 16 bit port (sends 3 packets to fill 2 pixels).
 
Thanks

    The PIC24 is a 16-bit processor.  It can't read or write more than 16 bits at a time to any register.

    Look at the 32 bit PIC32 products

    PIC32 only has 16-bit ports.
     
    However, PIC32MZxxDA has built-in LCD interface.

    From PIC32MM datasheet, chapter 10.6:

    "Port merging creates a 32-bit wide port from two GPIO
    ports. When the PORT32 bit is set, the next I/O port is
    mapped to the upper 16 bits of the lower port."
