15.7.1 Port E Data Register
Technical Data
328
NOTE:
Address:
Port E is an 8-bit special function port that shares three of its pins with
the timer A interface module (TIMA) and five of its pins with the timer B
interface module (TIMB).
The port E data register (PTE) contains a data latch for each of the eight
port E pins.
PTE[7:0] — Port E Data Bits
Data direction register E (DDRE) does not affect the data direction of
port E pins that are being used by the TIMA or TIMB. However, the
DDRE bits always determine whether reading port E returns the states
of the latches or the states of the pins.
Reset:
Read:
Write:
PTE[7:0] are read/write, software-programmable bits. Data direction
of each port E pin is under the control of the corresponding bit in data
direction register E.
