The temporary baud window
debug screen when the baud (BAUD) command is entered. The BAUD
command sets the baud rate for communications between the system
controller and the host computer. This window shows the available baud
rates.
Depending on the EM board used, the MMDS platform board can supply
the oscillator clock for the MCU's OSC1 input. This clock source can be
an internally generated source or an external source input through the
white logic clip of pod A. Note that the EM being used will require a
specific jumper configuration in order to use the platform board clock
source. Refer to the EM user's manual for the availability of this feature.
For the MMDS05, five clock frequencies are available. The four
internally generated clock frequencies are: 8 MHz, 4 MHz, 2 MHz, and 1
MHz, and an external clock source. Entering emulator clock (OSC)
command without the designated frequency brings up the temporary
MMDS emulator clock frequency window near the center of the debug
screen. Use the up/down arrow keys to select the emulator MCU's clock
frequency and press <CR> to complete the selection. The default
emulator clock rate is 2 MHz as shown in
