SCTimer/PWM output dynamic characteristics

Tamb = 40 C to +85 C; 2.4 V <= VDD <= 3.6 V; CL = 10 pF. Simulated skew (over process, voltage,

and temperature) of any two SCTimer/PWM output signals routed to standard I/O pins; sampled at

the 50 % level of the falling or rising edge; values guaranteed by design.
