1. NC (not-connected) pins are not bonded. They must be configured by software to output push-pull and forced to 0 in the

output data register to avoid an extra current consumption in low-power modes. list of pins: PI8, PI12, PI13, PI14, PF6, PF7,

PF8, PF9, PC2, PC3, PC4, PC5, PI15, PJ0, PJ1, PJ2, PJ3, PJ4, PJ5, PH6, PH7, PJ12, PJ13, PJ14, PJ15, PG14, PK3,

PK4, PK5, PK6 and PK7.

2. PC13, PC14, PC15 and PI8 are supplied through the power switch. Since the switch only sinks a limited amount of current

(3 mA), the use of GPIOs PC13 to PC15 and PI8 in output mode is limited: - The speed should not exceed 2 MHz with a

maximum load of 30 pF. - These I/Os must not be used as a current source (e.g. to drive an LED).

3. FT = 5 V tolerant except when in analog mode or oscillator mode (for PC14, PC15, PH0 and PH1).

4. If the device is in regulator OFF/internal reset ON mode (BYPASS_REG pin is set to VDD), then PA0 is used as an internal

reset (active low).

5. Internally connected to VDD or VSS depending on part number.
