i'am working with the DEMOQE board from PEmicro. Daugther Card: MC9S08QE8
I have a problem with the External Clock Source, an 32.768 kHz crystal. (C8, C9, Rf not populate) The FLL is in FEE Mode, but the crystal doesn't work.
ICSC1 = 0x00; /* Initialization of the ICS control register 1 */ /* ICSC2: BDIV=0,RANGE=0,HGO=0,LP=0,EREFS=1,ERCLKEN=1,EREFSTEN=1 */ ICSC2 = 0x07; /* Initialization of the ICS control register 2 */ while(!ICSSC_OSCINIT) { } /* Wait until the initialization of the external crystal oscillator is completed */ /* ICSSC: DRST_DRS=0,DMX32=1 */ /* Initialization of the ICS status and control */ ICSSC = (ICSSC & (unsigned char)~0xC0) | (unsigned char)0x20;
The same Code with the MC9S08QE128 Daughter Card works.
I seem to have the saem probem. The xtal works on a DEMOQE128, it worked on a SOIC28 QE8 but not on a SOIC20 pin package. ( no external parts,as per spec). Which package are you using?
