(1) Total device C_pd for multiple (n) outputs switching and (y) clocks inputs switching = {n * C_pd (each output)} + {y * C_pd (each clock)}
(2) C_pd (each bit) is the C_pd for each data bit (input and output circuitry) as it operates at 5 MHz (the clock is operating at 10 MHz in this
test, but its I_CC component has been subtracted out).
(3) C_pd (each clock) is the C_pd for the clock circuitry only as it operates at 10 MHz.
