Freescale Semiconductor
One 16-bit, 6-channel timer interface module (TIM2) with selectable input capture, output compare,
and pulse-width modulation (PWM) capability on each channel
Timebase module with clock prescaler circuitry for eight user selectable periodic real-time
interrupts with optional active clock source during stop mode for periodic wakeup from stop using
an external crystal
24-channel, 10-bit successive approximation analog-to-digital converter (ADC)
8-bit keyboard wakeup port with software selectable rising or falling edge detect, as well as high or
low level detection
Up to 53 general-purpose input/output (I/O) pins, including:
–
40 shared-function I/O pins, depending on package choice
–
Up to 13 dedicated I/O pins, depending on package choice
Selectable pullups on inputs only on ports A, C, and D. Selection is on an individual port bit basis.
During output mode, pullups are disengaged.
Internal pullups on IRQ and RST to reduce customer system cost
High current 10-mA sink/source capability on all port pins
Higher current 20-mA sink/source capability on PTC0–PTC4 and PTF0–PTF3
User selectable clockout feature with divide by 1, 2, and 4 of the bus frequency or the crystal
frequency
User selection of having the oscillator enabled or disabled during stop mode
BREAK module (BRK) to allow single breakpoint setting during in-circuit debugging
