I want to read the RCCR0 register then load it into the RCCR register to accurately set my clock speed. I tried using a pointer to address (0x01000h) as it states in the user manual but this didn't seem to work. Any ideas???

In cosmic you would define the locations:

const BYTE RCCR0 @0xFFDE;

const BYTE RCCR1 @0xFFDF;

RCCR = RCCR0; // load calibration value

in asm:

#define RCCR0 $FFDE

#define RCCR0 $FFDF

ld A, RCCR0

ld RCCR, A ; load calibration value
