Alternate Functions of Port A
• Bit 4 – 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 “Con-
figuring the Pin” for more details about this feature.
The Port A has an alternate function as the address low byte and data lines for the External
Memory Interface.
The Port A pins with alternate functions are shown in
Table 9-3.
The alternate pin configuration is as follows:
• AD7 – Port A, Bit 7
AD7, External memory interface address 7 and Data 7.
• AD6 – Port A, Bit 6
AD6, External memory interface address 6 and Data 6.
• AD5 – Port A, Bit 5
AD5, External memory interface address 5 and Data 5.
• AD4 – Port A, Bit 4
AD4, External memory interface address 4 and Data 4.
• AD3 – Port A, Bit 3
AD3, External memory interface address 3 and Data 3.
• AD2 – Port A, Bit 2
AD2, External memory interface address 2 and Data 2.
• AD1 – Port A, Bit 1
AD1, External memory interface address 1 and Data 1.
• AD0 – Port A, Bit 0
AD0, External memory interface address 0 and Data 0.
