Hi,
I need a crystal source for the ATxmega128-A1 on my Xplained Xmega-A1 board.
Since 12MHz oscillator of the AT32UC3B1256 is only 2cm far from PR1 pin of J3, I tried to strap 'TP OSC' (connected to XOUT0 of AT32UC3) with PR1 of ATxmega.
I am using this code but it blocks when waiting for XOSCRDY (seems to be not stable ?) :
CLKSYS_Prescalers_Config( CLK_PSADIV_2_gc, CLK_PSBCDIV_1_1_gc );
OSC.XOSCCTRL=OSC_FRQRANGE_12TO16_gc|OSC_XOSCSEL_EXTCLK_gc;
CLKSYS_Enable( OSC_XOSCEN_bm ); //enable ext oscillator
do {} while ( CLKSYS_IsReady( OSC_XOSCRDY_bm ) == 0 );
/* OSC.PLLCTRL=(OSC_PLLSRC_XOSC_gc|(5<<OSC_PLLFAC_gp)); //PLL input=12M, fact=5
CLKSYS_Enable( OSC_PLLEN_bm ); //enable PLL
do {} while ( CLKSYS_IsReady( OSC_PLLRDY_bm ) == 0 );
*/ CLKSYS_Main_ClockSource_Select( CLK_SCLKSEL_XOSC_gc );
// CLKSYS_Main_ClockSource_Select( CLK_SCLKSEL_PLL_gc );
Is someone has a clue ?
Best Regards
Doom
