PORTE is an internal data latch that can be accessed at two locations. PORTE can be
read or written at any time. If a pin in I/O port E is configured as an output, the corre-
sponding bit value is driven out on the pin. When a pin is configured for output, a read
of PORTE returns the latched bit value; when a pin is configured for input, a read re-
turns the pin logic level.
Bits in this register control the direction of the port E pin drivers when pins are config-
ured for I/O. Setting a bit configures the corresponding pin as an output; clearing a bit
configures the corresponding pin as an input. This register can be read or written at
any time.
Bits in this register determine the function of port E pins. Setting a bit assigns the cor-
responding pin to a bus control signal; clearing a bit assigns the pin to I/O port E.
