Family Configurations
Freescale Semiconductor
7
— 16-bit counter
— Selectable as free running or count down
Real-Time Clock (RTC)
— Maintains system time-of-day clock
— Provides stopwatch and alarm interrupt functions
Software watchdog timer
— 32-bit counter
— Low-power mode support
Clock generation features
— Crystal, on-chip trimmed relaxation oscillator, or external oscillator reference options
— Trimmed relaxation oscillator
— Pre-divider capable of dividing the clock source frequency into the PLL reference frequency range
— System can be clocked from PLL or directly from crystal oscillator or relaxation oscillator
— Low power modes supported
—2n (0
n 15) low-power divider for extremely low frequency operation
Interrupt controller
— Uniquely programmable vectors for all interrupt sources
— Fully programmable level and priority for all peripheral interrupt sources
— Seven external interrupt signals with fixed level and priority
— Unique vector number for each interrupt source
— Ability to mask any individual interrupt source or all interrupt sources (global mask-all)
— Support for hardware and software interrupt acknowledge (IACK) cycles
— Combinatorial path to provide wake-up from low-power modes
DMA controller
— Four fully programmable channels
— Dual-address transfer support with 8-, 16-, and 32-bit data capability, along with support for 16-byte (4
32-bit)
burst transfers
— Source/destination address pointers that can increment or remain constant
— 24-bit byte transfer counter per channel
— Auto-alignment transfers supported for efficient block movement
— Bursting and cycle-steal support
— Software-programmable DMA requests for the UARTs (3) and 32-bit timers (4)
Reset
— Separate reset in and reset out signals
— Seven sources of reset:
– Power-on reset (POR)
– External
–Software
– Watchdog
– Loss of clock
– Loss of lock
– Low-voltage detection (LVD)
— Status flag indication of source of last reset
Chip configuration module (CCM)
— System configuration during reset
