I need to access the RTC registers of the ST10F269 controller, but the compiler does not recognize these registers. I have tried to access these registers with the sfr keyword, but it does not help since it is an XBUS peripheral. What is the correct way to access the RTC?
You need to define the XBUS peripherals as pointer constants as shown below:
#define RTCCON (*((unsigned int volatile sdata *) 0xEC00))
Using this define, you can access the RTCCON register as normal C variable.
