OSC

A.1.6.7 Short Description

selects Emulator Clock Frequency command.

A.1.6.8 Syntax

OSC [rate source]

A.1.6.9 Description

The OSC command selects the emulator clock frequency: one of five internally generated frequencies (16 Mhz, 8 Mhz, 4 Mhz, 2 Mhz, or 1 Mhz), or an external clock source. The firmware sets the default emulator clock rate, adapting it to the current frequency.

Entering this command without parameters opens the corresponding dialog box.

OSC [rate source]

where rate is: OSC1MHZ	Selects the 1 Mhz oscillator.
OSC2MHZ	Selects the 2 Mhz oscillator.
OSC4MHZ	Selects the 4 Mhz oscillator.
OSC8MHZ	Selects the 8 Mhz oscillator.

	OSC16MHZ Selects the 16 Mhz oscillator.
	Where source is: EXT	Selects an external clock source.
