1.6.2 Oscillator Pins (PTE4/OSC1 and PTE3/OSC2)
PTE4/OSC1 and PTE3/OSC2 are general-purpose, bidirectional I/O
port pins. These pins can also be programmed to be the connections for
an external crystal, resonator or clock circuit. See Section 7. Internal
Clock Generator (ICG) Module.
1.6.3 External Reset Pin (RST)
A logic 0 on the RST pin forces the MCU to a known startup state. RST
is bidirectional, allowing a reset of the entire system. It is driven low when
any internal reset source is asserted. This pin contains an internal pullup
resistor. See Section 19. System Integration Module (SIM).
1.6.4 External Interrupt Pin (IRQ)
IRQ is an asynchronous external interrupt pin. This pin contains an
internal pullup resistor. See Section 12. External Interrupt (IRQ).
