The data sheet for the MEGA 1280 states that there are 12 PWM pins, Table 3-1 page 7.
However, after rading the Port discriptions, there are 15 pwm pins.
Port B = 4
Port E = 3
Port G = 1
Port H = 4
Port L = 3
Total = 15
Further more, a Schematic for the Arduino MEGA shows 5 pwm pins on Port E or a total of 17. PE_0 and PE_1 which are listed in the data sheets as TXD0 and RXD0, not as PWMs.
Even if we ignore those, there is still 3 pins left that are extra. So, is there actually 15 PWMs and the Data sheet stateing 12 incorrect?
What am I missing?
