A module on the microcontroller is configured using a control register called CTL that has the format shown below SLP CLK CAP IE 2- 2- 1- . SLP: selects sleep mode; value between 0 and3 CLK: selects clock speed: value between 0 and 7 . CAP: selects built-in capacitor value; choice between 0 and 3 IE: interrupt enable bit (1: enable/ 0: disable) 3- To support programming the device, the environment has declared the symbolic constants SLP 3: SLP 2 SLP 1 SLP 0 1100 0000 1000 0000 0100 0000 CLK 7 CLK 6: 0011 1000 0011 0000 CLK 0 CAP_3: 0000 0110 A module on the microcontroller is configured using a control register called CTL that has the format shown below SLP CLK CAP IE 2- 2- 1- .
