Preliminary
Freescale Semiconductor
7
— Fully compatible with industry-standard I
2
C bus
— Master or slave modes support multiple masters
— Automatic interrupt generation with programmable level
Queued Serial Peripheral Interface (QSPI)
— Full-duplex, three-wire synchronous transfers
— Up to four chip selects available
— Master mode operation only
— Programmable master bit rates
— Up to 16 pre-programmed transfers
Four 32-bit DMA Timers
— 13-ns resolution at 75 MHz
— Programmable sources for clock input, including an external clock option
— Programmable prescaler
— Input-capture capability with programmable trigger edge on input pin
— Output-compare with programmable mode for the output pin
— Free run and restart modes
— Maskable interrupts on input capture or reference-compare
— DMA trigger capability on input capture or reference-compare
Four Periodic Interrupt Timers (PITs)
— 16-bit counter
— Selectable as free running or count down
Software Watchdog Timer
— 16-bit counter
— Low power mode support
Phase Locked Loop (PLL)
— Crystal or external oscillator reference
— 8 to 25 MHz reference frequency for normal PLL mode
— 24 to 75 MHz oscillator reference frequency for 2:1 mode
— Separate clock output pin
Interrupt Controllers (x2)
— Support for up to 110 interrupt sources organized as follows:
– 103 fully-programmable interrupt sources
– 7 fixed-level external interrupt sources
— Unique vector number for each interrupt source
— Ability to mask any individual interrupt source or all interrupt sources (global mask-all)
