How can I set SPI pin_x at PIC24FJ256GB106

My PIC is PIC24FJ256GB106.
How should I plan "PRn Pin" for Hardware ?
24FJ256GB106 have three hardware SPI inside.
How does CCS plan the code edit ?

The CCS index say ~

Code:

#use spi(DI=PIN_B1, DO=PIN_B0, CLK=PIN_B2, ENABLE=PIN_B4, BITS=16)
// uses software SPI

#use spi(FORCE_HW, BITS=16, stream=SPI_STREAM)
// uses hardware SPI and gives this stream the name SPI_STREAM

But ~ When I use hardware SPI and compiler.

CCS have error about "not valid for H/W" <-----

I hope SPI plan use ~

Code:

#define SDI PIN_B4
#define SDO PIN_B5
#define SCK PIN_B8
#define CS PIN_B9

How can I write the CCS code?　

Help me, please .... Thanks everybody Very Happy

PIC24 with remappable I/O pins are supported by #pin_select statements in PCD. Examples have been given in CCS Forum.
