Freescale Semiconductor
A logic 0 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. This pin contains an internal pullup
resistor. See
IRQ1 is an asynchronous external interrupt pin. This pin contains an
internal pullup resistor. See
