Hello Tsuneo,

Still EXTERN_ALLOCATE is effecting my code.
I have written a small code,if i include #define EXTERN_ALLOCATE i could see pulses on PE.0 pin?without EXTERN_ALLOCATE PE.0 pin is high.

  main()
  {
   CPUCS = ((CPUCS & ~bmCLKSPD) | bmCLKSPD1) ;
   IFCONFIG |= 0xC0;
   SYNCDELAY;
   PORTACFG |= 0x08;
   SYNCDELAY; 
   OEE = 0x01;
   SYNCDELAY; 
   IOE &= ~0x01; // clear bit 0 
   IOE |=  0x01; // set bit 0
  }
