I rechecked my work to be sure, this is my busiest 40-pin PIC that I mentioned previously:

- 16 rotary encoders pins pulled HIGH,
- 4 momentary switches pulled HIGH,
- 2 ADC inputs,
- 2 PWM:
__- pin for LCD backlight, 3mA (2N2907)
__- pin for LED strip, 0.0mA (IRFZ44N) - so low it doesn't even register on my ordinary multimeter.
- USART TX and RX pins pulled HIGH,
- remaining unused pins are output pulled LOW

(waiting for new fuses to retest using my TES multimeter)
