Disable Pull-up resistor atmega328p (by Alex)
Is it correct if i use "move 0x14 to #0x35 register" to disable pull up resistor of an arduino nano, want to know if it is okay? don{t want to enable something unnecessary

Bit 4 – PUD: Pull-up Disable
equal to mask 0x10, not 0x14.

Move 0x10 to #0x55 register to disable all pull-up resistors for
ATmega48PA/88PA/168PA/328P

Excellent, also a good tutorial for using setbit and clrbit.
It looks like version V4400 is stable, still no bugs found.
Thx.
