Alternate I/O Functions of PortE
PortE Schematics
immediately tri-state. This function happens only if the Check pin has been enabled in the sys-
tem control register. The use of the Check pin will NOT disable the use of that pin as an input to
PE7 nor as an input as alternate INT3.
PortE may also be used for various Timer/Counter functions, such as External Input Clocks
(TC0 and TC1), Input Capture (TC1), Pulse Width Modulation (TC0, TC1 and TC2), and toggling
upon an Output Compare (TC0, TC1 and TC2). For a detailed pinout description, consult
4-35 on page
page 89.
Note that all port pins are synchronized. The synchronization latches are, however, not shown in
the figures.
