Alternate Functions of Port A
66
ATmega8515(L)
• 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 “Configuring the Pin” on page 60 for more details about this feature.
Port A has an alternate function as the address low byte and data lines for the External
Memory Interface.
Table 26. Port A Pins Alternate Functions
Table 27 and Table 28 relate the alternate functions of Port A to the overriding signals
shown in Figure 33 on page 64.
