Configuration Register
//
// All macro-based register writes follow the same basic format. For
// single-instance modules, you may use the simpler AM_REG macro. For
// multi-instance macros, you will need to specify the instance number using
// the AM_REGn macro format.
//
// AM_REG(<MODULE>, <REGISTER>) |= AM_REG_<MODULE>_<REGISTER>_<FIELD>_<VALUE>;
// AM_REGn(<MODULE>, <INSTANCE>, <REGISTER>) |= AM_REG_<MODULE>_<REGISTER>_<FIELD>_<VALUE>;
//
// For registers that do not have specific enumeration values, you may use this alternate format instead.
//
// AM_REG(<MODULE>, <REGISTER>) |= AM_REG_<MODULE>_<REGISTER>_<FIELD>(<NUMBER>);
//
// For example, the following three lines of code are equivalent methods of
// writing the value for 12MHZ to the CLKSEL field in the ADC_CFG register.
//
AM_REG(ADC, CFG) |= AM_REG_ADC_CFG_CLKSEL_12MHZ;
AM_REGn(ADC, 0, CFG) |= AM_REG_ADC_CFG_CLKSEL_12MHZ;
AM_REG(ADC, CFG) |= AM_REG_ADC_CFG_CLKSEL(0x1);
