Port E is an 8-bit bi-directional I/O port with internal pull-up resistors.
Three I/O memory address locations are allocated for the Port E, one each for the Data
Register – PORTE, $03($23), Data Direction Register – DDRE, $02($22) and the Port E
Input Pins – PINE, $01($21). The Port E Input Pins address is read-only, while the Data
Register and the Data Direction Register are read/write.
The Port E output buffers can sink 20 mA. As inputs, Port E pins that are externally
pulled low will source current if the pull-up resistors are activated.
All Port E pins have alternate functions as shown in Table 33.
Table 33. Port E Pin Alternate Functions
Port Pin
Alternate Function
PE0
PDI/RXD (Programming Data Input or UART Receive Pin)
PE1
PDO/TXD (Programming Data Output or UART Transmit Pin)
PE2
AC+ (Analog Comparator Positive Input)

PE4
INT4 (External Interrupt4 Input)
PE5

PE6

PE7

When the pins are used for the alternate function, the DDRE and PORTE Registers
have to be set according to the alternate function description.
