PortE
Table 4-34.
Note:
Figure 4-52. PortD Schematic Diagram
PortE is an 8-bit bi-directional I/O port with internal pull-up resistors.
Three I/O memory address locations are allocated for the PortE, one each for the Data Register
– PORTE, $07($27), Data Direction Register – DDRE, $06($26) and the PortE Input Pins –
PINE, $05($25). The PortE Input Pins address is read only, while the Data Register and the
Data Direction Register are read/write.
The PortE output buffers can sink 20 mA. As inputs, PortE pins that are externally pulled Low
will source current if the pull-up resistors are activated.
All PortE pins have alternate functions as shown in
