SYSTEM DESIGN
Table 7-1 lists the interrupt signals that are multiplexed with other microcontroller functions.
Pinstraps are sampled only at external reset and do not affect the pin’s other functions, so
they are not shown in this table. Other multiplexed signals, when enabled, either disable or
alter any other functions that use the same pin.
For diagrams of some example applications, see Chapter 3, “System Overview.”
