PORTF - Port F Data Register
DDRF - Port F Data Direction Register
PINF - Port F Input Pins Address
PORTG - Port G Data Register
DDRG - Port G Data Direction Register
PING - Port G Input Pins Address
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).
