dsPIC33EP512MU810 uart pins

Can someone please tell me what pin numbers on the dsPIC33EP512MU810 IC are the pin to use for U1, U2, U3, and U4 UART's?
and tell me where you found that info?  i don't see it in the data sheet.

    (I didn't even look into the datasheet, so no references...)
    If it's got that many UARTs, some if not all have their I/O pins assigned via the PPS configuration registers. So look into the chapters U(S)ART and PPS.

    PEBKAC / EBKAC / POBCAK / PICNIC (eventually see en.wikipedia.org)

    All is the corect answer. wink: wink
    I'm not aware of any 16-bit PIC with PPS having dedicatd pins for any of its UARTs.

    Latest datasheet is at http://ww1.microchip.com/...n/DeviceDoc/70616g.pdf
    Page 26 tells you U1TX, U1RX etc are all assigned by PPS
    http://ww1.microchip.com/...Doc/70616g.pdf#page=26
     
    Section "11.4 Peripheral Pin Select" introduces PPS
    http://ww1.microchip.com/...oc/70616g.pdf#page=210
     
     The registers for mapping inputs U1RX to U4RX are in the table on pages 211-212 and the values to put into them for each pin are in the table on pages 231-214
     
    The output mappings for U1TX to U4TX are on pages 215-216
     
    Read this chapter carefully. It is a great facility once you get your head around it.
