True. For some reason I've always found that clumsy. For one thing need a third definition for reading the bit: #define ADC_ENABLE (ADC_PORT & ADC_ENABLE_BIT) Except that conflicts with with the macro you use to set bit. It always seemed so much cleaner to just do this: #define ADCEnable P3OUTb.b3 -- Grant Edwards gra...@visi.com
