PINF – Port F Input Pins Address
PORTG – Port G Data Register
DDRG – Port G Data Direction Register
PING – Port G Input Pins Address
SFIOR – Special Function IO Register
Note that PORTF and DDRF Registers are not available in ATmega103 compatibility mode
where Port F serves as digital input only.
Note that PORTG, DDRG, and PING are not available in ATmega103 compatibility mode. In the
ATmega103 compatibility mode Port G serves its alternate functions only (TOSC1, TOSC2, WR,
RD and ALE).
• Bit 2 – PUD: Pull-up disable
When this bit is written to one, the pull-ups in the I/O ports are disabled even if the DDxn and
PORTxn Registers are configured to enable the pull-ups ({DDxn, PORTxn} = 0b01). See
