Electrical characteristics  
supply voltage to supply the I/O pin circuitry and to charge/discharge the capacitive load  
(internal or external) connected to the pin:  
ISW = VDD × fSW × C  
where  
I
is the current sunk by a switching I/O to charge/discharge the capacitive load  
is the MCU supply voltage  
SW  
V
DD  
f
is the I/O switching frequency  
SW  
C is the total capacitance seen by the I/O pin: C = C + C  
INT  
EXT  
The test pin is configured in push-pull output mode and is toggled by software at a fixed  
frequency.
