Parallel Input/Output
4.7.1 PORTE — Port E data register
4.8 Port F
Technical Data
Port E data (PORTE)
NOTE:
This is a read-only register and is not affected by reset. The bits may be
read at any time.
As port E shares pins with the A/D converter, a read of the this register
may affect any conversion currently in progress, if it coincides with the
sample portion of the conversion cycle. Hence, normally port E should
not be read during the sample portion of any conversion.
Port F is an 8-bit bidirectional port, with both data and data direction
registers. In addition to their I/O capability, port F pins are used as the
non-multiplexed low order address pins, as shown in the following
table.
The state of the pins on reset is mode dependent. In single chip or
bootstrap mode, port F pins are high-impedance inputs with selectable
internal pull-up resistors (see
expanded or test modes, port F pins are low order address outputs and
PORTF/DDRF are not in the memory map.
