Port A–D Alternate Function Subregisters
Description
Port Alternate Function Enabled
0 = The port pin is in normal mode and the DDx bit in the Port A–D Data Direction subregister
1 = The alternate function selected through Alternate Function Set subregisters is enabled.
AF7
If 02H in Port A–D Address Register, accessible through the Port A–D Control Register
determines the direction of the pin.
Port pin operation is controlled by the alternate function.

The Port A–D Alternate Function Subregister, shown in Table 22, is accessed through the
Port A–D Control Register by writing
D Alternate Function subregisters enable the alternate function selection on pins. If dis-
abled, pins functions as GPIO. If enabled, select one of four alternate functions using
alternate function set subregisters 1 and 2 as described in the
Function Set 1 Subregisters
page 37 and
the
ciated with each port pin.
Port A–D Output Control Subregisters
The Port A–D Output Control Subregister, shown in Table 23, is accessed through the Port
A–D Control Register by writing
the Port A–D Output Control subregisters to 1 configures the specified port pins for open-
drain operation. These subregisters affect the pins directly and, as a result, alternate func-
tions are also affected.
Do not enable alternate functions for GPIO port pins for which there is no associated al-
ternate function. Failure to follow this guideline can result in unpredictable operation.
