Freescale Semiconductor
The OSC1 and OSC2 pins are the connections for the on-chip oscillator
circuit. (See
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. (See
Integration Module (SIM)
IRQ is an asynchronous external interrupt pin. (See
External Interrupt
V
modules are the analog-to-digital converter (ADC) and the clock
generator module (CGM). (See
(CGM)
The V
connections for the analog sections of the circuit and should be
decoupled as per the V
of a clock generator module (CGM) and an analog-to-digital converter
(ADC). V
