Bus State Analysis
MOTOROLA
Other function keys in the setup screen allow for clearing of the setup
screen as well as storing and using setup files. To cancel the entire bus
state analyzer setup, press <ESC>. To clear the setup screen, making it
ready to redefine events and reselect a mode, press the F8 key.
To save this bus state analyzer setup to a file, press the F6 key: a
subordinate window prompts for a filename. To load a bus state analyzer
setup already saved to a file, press the F5 key: a subordinate window
prompts for the filename. Entering the filename fills in the setup-screen
values; press the F7 key to return to the debug screen. (An alternative
way to load a saved setup is to enter the LOADTRIGGERS command
from the debug screen. This method bypasses the setup screen.)
Selecting Options
An optional part of analyzer setup is specifying the frequency and source
of the time tag clock. This clock provides a time reference value in each
frame of the trace buffer. (
Using the Time-Tag Clock
gives more
information about the time tag clock.) Enter the time tag clock source
(TIMETAG) command; this command brings up the small time-tag
window in the center of the debug screen. This window gives you these
choices (16 Mhz is the default):
16 Mhz
Selects the 16 MHz oscillator.
8 Mhz
Selects the 8 MHz oscillator.
4 Mhz
Selects the 4 MHz oscillator.
2 Mhz
Selects the 2 MHz oscillator.
1 Mhz
Selects the 1 MHz oscillator.
External
Selects the external clock
Programmable
Selects the programmable clock.
Emulator
Selects the emulator clock, the bus clock of the
emulating MCU.
If you select
External, connect the TT_OSC clip (white) of the pod B
cable to the external clock source. (The pod B connector is the closest
to the front of the station module.
