The Emulator Clock/Target System Clock is not present.
SOLUTION:
Ensure you have a clock present at all times. If a clock is not present,
configure the target system clock via a jumper on the daughter board to select
the internal emulator clock or the user target system clock.
Breakpoints disappear on download.
SOLUTIONS:
If breakpoints disappear when you download a file, the global switch, Clear
Memory on Download, may be selected in the Options > Environment Setup
dialog box.
With the Clear Memory on Download option selected, the MPLAB IDE
software will clear emulation memory before downloading a file.
Double click the breakpoints toggle in the status bar to turn breakpoints on
and off.
Stack overflow or underflow keeps occurring.
Stack overflow or underflow may occur when emulating some PICmicro MCU
devices. The following details the ICEPIC In-Circuit Emulator hardware stack
levels by family:
• If the emulator is to provide the system clock from the on-board canned
• If the clock on the target application is to provide the system clock, set
• 2-Levels Deep Hardware Stack (PIC16C5X)
• 8-Levels Deep Hardware Stack (PIC16CXXX)
oscillator, set the internal clock jumper (INTCLK).
the external clock jumper (EXTCLK).
Some data may be left in the stack as the PIC16C5X device has no way
to clear the stack. No overflow or underflow is supported for the
PIC16C5X.
The Host Software displays an underflow or overflow message when you
set Stack Break Enable on the Hardware configuration display and push
or pop the stack beyond its limit. Select Options > Processor Setup >
Hardware to display the Hardware configuration dialog box.
Note:
CMOS clock levels are required and a crystal CANNOT be
used.
