Design an embedded system, where the Software in C will generate, A. IKHZ signal with a duty cycle of 75% on pin P1.0. When button is pressed on pin 1.1, The signal toggles to B. 2KHZ signal with a duty cycle of 25% on pin P1.0. The signal toggles from case A to B and vice versa whenever a button on pin P1.1 is pressed. Draw the timing diagram generated on a paper. It should show the time-period and duty cycle of a signal clearly. Use interrupts for button press and low power mode. Draw the schematic.
