I am using a Cortex-M0 with Keil uVision4.  How are constants located in program memory and how can these program memory constants be changed by code?

    I want to store calibration constants for an external sensor in program flash since there is no onboard EEPROM. I have code that performs the calibration and determines the constants. Most MCU's that I have worked with have assembler commands that write directly to program flash.
