I want to Provide FPU enablement and support on NXPS32K38. So, I want to detect the exceptions of IOC and DZC and raise an Interrupt accordingly whenever the system notices a DZC or IOC and perform exception handling. I want to retrieve the data using which these exceptions are getting raised. Like if there is an 5/0 operation and the ISR is raised I want to retrieve these values 5 and 0 in ISR and use these to do the exception handling mechanism. As per the datasheet/Reference Manual, the info regarding these were captured using the FPCCR extended stack frame and the FPU S0-S31 registers capture the information. But while I am trying to access the registers, I am getting the same values all the time even after I try to change the exception raising mechanism. So, does it mean the S0-S31 registers doesn't contain the information of such exceptions? If yes, where can I get this control data from?
