1.14 The option “Always treat variables of enumerator type with unknown size
as 1 byte”
The “Always treat variables of enumerator type with unknown size as 1 byte” option is effective
after downloading the program. When the option status is changed, target program should be
downloaded again.
And also, this option is effective for all variables of enumerator type in the program, even if the
compiling options are different for each file.
1.15 Debugging for assembler macros
When the break points are set at the assembler macro codes, the break points would be set at the
different address or not be displayed as the PC line.
1.16 Debugging for inline functions
When stepping the function including the call for a inline function, local variables would not be
able to be referred.

1.20 Notes on Debugging (M16C PC4701 Emulator Debugger)
1.20.1 Variables assigned to registers
When you build a target program, IAR EWM16C may generate the warning like following:
Warning [w23]: Cannot represent location of Register pair variable
'R1H:R1L'
In this case, you can not see the variable, which is assigned to R1 in the emulator software.
IAR will fix it by upgrading XLINK in near future. Please ask IAR about it for more details.
1.20.2 In the case of using PC4701M with IAR’s cross tools
When you have all the following conditions at once, the IAR’s cross tools may not work correctly.
- Using the PC4701M in ECP mode of LPT connection
- The M16C PC4701 emulator software running
