// psv2010.c 
// This simple program shows how PSV is done on a dsPIC using a
// MCLV demo board.  A character string is stored in PM
// as a constant.  It is automatically retreived as data memory
// by the C30 compiler using the PSV feature of dsPIC.
// To view the whole data and program memory mapping, create a
// *.map file in MPLAB and use the editor to view it after a compile.
// The user must connect a Hyperterm program to the UART and hit SW1
// on the PICDEM MCLV, to transmit a character string stored in PM.  
// The string will then be displayed in Hyperterm set at 19200 baud.
