The program goes into the weeds when I attempt to erase a block of intenal flash.

section RX ".driver" ".driver"
INT_FLASHER void vIntFlashEraseCalledFromRam( )

BYTE bStatus;

/* STEP 1: Set up the internal flash configuration register to erase. */
FLASH.MCR.B.ERS = 1;
/* STEP 2: Select Block L3 for erase. */
FLASH.LMSR.B.LSEL = INT_FLASH_L3;
/* STEP 3: Perform erase interlock write (write to any address in flash). */
*((VULONG *)0x0001C000L) = 0xFFFFFFFF;
/* STEP 4: Start internal erase sequence by writing 1 to EHV register. */
FLASH.MCR.B.EHV = 1;
/* STEP 5: Wait for done bit to be set. */
while( !FLASH.MCR.B.DONE )
{
}
/* STEP 6: Operation complete, check erase status. */
bStatus = FLASH.MCR.B.PEG;
/* Step 7: End interal erase sequence. */
FLASH.MCR.B.EHV = 0;
FLASH.MCR.B.ERS = 0;
}/* vIntFlashEraseCalledFromRam() */
