Syntax
CONFIG OSC=ENABLED|DISABLED , PLLOSC=ENABLED|DISABLED, EXTOSC=ENABLED|DISABLED, 32KHZOSC=ENABLED|DISABLED, 32MHZOSC=ENABLED|DISABLED, RANGE=range, 32KHZPOWERMODE=powermode, STARTUP=startup , PLLSOURCE=pll , PLLDIV2=plldiv ,PLLMUL=pllmul
Remarks
|
OSC |
Use ENABLED to enable the internal 2 MHZ oscillator. This oscillator is enabled by default. Use DISABLED to disable the internal oscillator. |
|
PLLOSC |
Use ENABLED to enable the PLL oscillator. The oscillator is disabled by default. |
|
EXTOSC |
Use ENABLED to enable the external oscillator. The external oscillator is disabled by default. |
|
32KHZOSC |
Use ENABLED to enable the internal 32 KHz oscillator. This oscillator is disabled by default. |
|
32MHZOSC |
Use ENABLED to enable the internal 32 MHz oscillator. This oscillator is disabled by default. |
|
RANGE |
Specify the range of the external oscillator. - 400KHZ_2MHZ - 2MHZ_9MHZ - 9MHZ_12MHZ - 12MHZ_16MHZ This option is only needed when using the external oscillator. |
|
32KHZPOWERMODE |
Select the power mode of the 32 KHz interal oscillator. This can be NORMAL or LOW_POWER. The default is NORMAL |
|
STARTUP |
The startup time can be specified. Use a value of : - EXTCLK (6 CLK) - 32KHZ (for 16 CLK) - XTAL_256CLK (for 256 CLK) - XTAL_1KCLK (for 1K CLK) - XTAL_16CLK (for 16K CLK) |
|
PLLSOURCE |
This option let you select the oscillator source of the PLL oscillator. Valid options are : - RC2MHZ , the internal 2 MHz oscillator (default) - RC32MHZ , the internal 32 MHz oscillator - EXTCLOCK , an external clock signal or oscillator |
|
PLLDIV2 |
This option let you select the PLL two divider. Valid options are ENABLED and DISABLED |
|
PLLMUL |
This option let you specify the PLL multiplication factor. The numeric value must be in the range from 1-31. A value of 0 disables the multiplication. |
