OSC
Select Emulator Clock Frequency
OSC
The MMDS platform board can supply an oscillator clock source for the
MCU’s OSC1 input.
For the MMDS05, five clock frequencies are available. The four
internally generated clock frequencies are available: 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.
For the MMDS08, six clock frequencies are available. The five internally
generated clock frequencies are available: 16 MHz, 8 MHz, 4 MHz, 2
MHz, and 1 MHz and an external clock source. The default emulator
clock rate is 4 MHz.
Entering this command without the < rate> argument brings up the EM
oscillator window. An oscillator frequency can be selected via this
window.
NOTE:
Many EMs require a specific jumper configuration in order to use this
clock source. Refer to the EM user's manual for EM clock source
information.
Syntax:
OSC [< rate> | <source>]
Where:
< rate> 8, 4, 2, or 1
< source> External
Examples:
>OSC 4 Use the 4-MHz internal emulator clock.
>OSC EX Use the external emulator clock.
>OSC Bring up the emulator clock window. The current
oscillator setting will be highlighted.
