HC9S08GW, small model, CW 10.2

Fixup overflow in MCU_init, to _ICSC1 type 1, at offset 0x17  
Fixup overflow in MCU_init, to _ICSC2 type 1, at offset 0x19  

Looking at MCU_init()  I expect these are at the offsets noted:

  ...
  ICSC1 = 0x04;                        /* Initialization of the ICS control register 1 */
  ICSC2 = 0x00; 

  ...

 

This does not seem to fit the JSR/BSR type problem, anyway I disabled all optimizations to no avail.  This is an uncomplicated project--just trying to get some sample I2C code running.  My title says Location Type because I saw it listed like that once, I don't see that now.

 

=========================

I'm new to CW, but prm-file doesn't seem to have anything discontiguous? unless it is PPAGE2 (which I don't understand)
