WinIDE Simulate PLL HC08

HI, All

I am a beginner to HC08 and ICS08GPGTZ. I wonder how to skip the below code

BRCLR 6,PBWC,*

in the ICS08GP In-Circuit Simulator when I simulate the code without connecting board?

I tried

bset 6,PBWC

But failed.

Thanks Zen

BRCLR 6,PCB,*

is a conditional delay based on a bit test on PBWC which is the lock bit of the PLL register. It translates in a 3 byte line of code and in an undetermined delay.

I cannot say anything for the delay but the instruction may be replaced by

NOP
NOP
NOP

which is 3 bytes long and takes 3 HC08 clock cycles just making nothing else. I think that this is ok for your simulation. The best approach is anyway to skip this line by a semicolon to make an easy restoration when compiled on the real board:

; BRCLR 6,PCB,*

Thanks Encoder,

You introduced two approaches to the above simulation problem. I will spend more time on the WinIDE tool.

Zen,

There are a couple other ways that you can surpass this line of code during your simulation session.

After loading your code into P&E ICS08 full chip simulation you can:

1. Use PC 'name of sub-routine or location of code' to set your program counter to correct line.

2. You can right click your mouse pointing to a particular location and choose to set your Program Counter to the place where your mouse is pointing.
