I have download from NXP demo example project for programming the internal flash memory of XEP controllers.
The project that I download is "XEP100-FLASH-PFLASH-CW51"
The project works just fine, but the problem that I am facing, is that it is not clear what is the correct frequency that I should enter in PFLASH_Init routine.
void PFLASH_Init(unsigned char fdiv)
while(FSTAT_CCIF == 0); //wait if command in progress
FCLKDIV = fdiv; //osc = 16MHz
the main calls it as follow
So, it gives 0x15 for 16MHz oscillation.
I will use the PLL with High speed (internal bus clock 50MHz), Low speed (internal bus clock 14.75MHz), Slow speed (internal bus clock 4MHz).
The problem is that PFLASH_Init has no comments about the formula of oscillation and the operant of "PFLASH_Init routine"
Could someone from NXP tell me how can I calculate the operant of "PFLASH_Init routine" when the internal bus clockis 50, 14.75 and 4MHz?
