1. The “Output Source Current” specification is applicable only to the Push-Pull I/O type.
2. This Specification indicates only one PWM driving capability, and there are totally five built-in drivers, user
can multiply the actual number of driver to get the total amount of current. (IPWM * N; N=0, 1, 2, 3, 4, 5)
