1.6.3 Oscillator Pins (OSC1 and OSC2)
The OSC1 and OSC2 pins are the connections for the on-chip oscillator
circuit.
1.6.4 External Reset Pin (RST)
A logic zero on the RST pin forces the MCU to a known start-up state.
RST is bidirectional, allowing a reset of the entire system. It is driven low
when any internal reset source is asserted. The RST pin contains an
internal pullup device to V_DD. (See Section 8. System Integration
Module (SIM).)
1.6.5 External Interrupt Pins (IRQ, PTE4/D–)
IRQ is an asynchronous external interrupt pin. IRQ is also the pin to
enter Monitor mode. The IRQ pin contains a software configurable pullup
device to V_DD. PTE4/D– can be programmed to trigger the IRQ interrupt.
(See Section 15. External Interrupt (IRQ).)
