Assume a 16MHz Fcy and a prescale value of 64 for Timer2 operation in 16 bit mode. Also assume that an output compare module com figured for pulse width modulation using a 20ms period is being used to control the speed of an DC motor. What OCXRS register value is required to run the motor at 1/4 full speed (assume a linear relationship between DC motor speed and pulse width)? Truncate any decimal part. a) 1000 Ob) 1150 O c) 1250 d) 1553
