i am using BF561 EZ kit lite Board Rev 2.3.Here i am trying to change the PLL settings and to monitor the above changes i am tapping the SCLK at Pin 85 of J2 extender.
my problem is that
1. whenever i use HPUSB ICE Emulator then any change in PLL_CTL register appears after i compile and run my code Twice.
2.when i fuse LDR to flash then even after booting again and again PLL_CTL change does not reflect in SCLK.
Here is my simple code :
unsigned int imask;
//Enable SCLK1 for asynchronous memory region accesses. So that we can probe on the SCLK1 signal
*pVR_CTL = 0x00DB;
*pSICA_IWR0 = 0x01;
*pSICA_IWR1 = 0x00;
imask = cli();
*pPLL_CTL = 0x2000 ;
*pPLL_DIV = 0x0006 ;
please reply as soon as possible.
