The Port A–D Address registers select the GPIO Port functionality accessible through the
Port A–D Control registers. The Port A–D Address and Control registers combine to pro-
vide access to all GPIO Port controls
PADDR[7:0]—Port Address
The Port Address selects one of the sub-registers accessible through the Port Control reg-
ister.
The Port A–D Control registers set the GPIO port operation. The value in the correspond-
ing Port A–D Address register determines which sub-register is read from or written to by
a Port A–D Control register transaction
Port Control sub-register accessible using the Port A–D Control Registers
No function. Provides some protection against accidental Port reconfiguration.
