Figure 51. Port B Schematic Diagram (Pin PB7)
Port C
Port C is an 8-bit bi-directional I/O port. Three I/O memory address locations are allo-
cated for the Port C, one each for the Data Register – PORTC, $15($35), Data Direction
Register – DDRC, $14($34) and the Port C Input Pins – PINC, $13($33). The Port C
Input Pins address is read-only, while the Data Register and the Data Direction Register
are read/write.
All port pins have individually selectable pull-up resistors. The Port C output buffers can
sink 20 mA and thus drive LED displays directly. When pins PC0 to PC7 are used as
inputs and are externally pulled low, they will source current if the internal pull-up resis-
tors are activated.
The Port C pins have alternate functions related to the optional external data SRAM.
Port C can be configured to be the high-order address byte during accesses to external
data memory. When Port C is set to the alternate function by the SRE (external SRAM
enable) bit in the MCUCR (MCU Control Register), the alternate settings override the
Data Direction Register.
