Controllers and Processors With
Bidirectional I/O Pins
Some microcontrollers have bidirectional reset pins.
Depending on the current drive capability of the control-
ler pin, an indeterminate logic level may result if there

4.7 k Ω resistor in series with the output of the TCM809/
TCM810 (Figure 4-3). If there are other components in
the system that require a reset signal, they should be

components are required to follow the reset I/O of the
microcontroller, the buffer should be connected as
shown with the solid line.
