— Sampling timer with interrupt
— Once-per-day, once-per-hour, once-per-minute, and once-per-second interrupts
— Operation at 32.768 kHz, 32 kHz, or 38.4 kHz (determined by reference clock crystal)
• Four 32-bit DMA timers
— 12.5-ns resolution at 80 MHz
— Programmable prescaler and sources for clock input, including an external clock option
— 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 and DMA trigger capability on input capture or output compare
• Software watchdog timer
— 16-bit counter
— Low-power mode support
• Four periodic interrupt timers (PITs)

— Support for hardware and software interrupt acknowledge (IACK) cycles
— Combinatorial path to provide wake-up from low power modes
• DMA controller
— 16 fully programmable channels with 32-byte transfer control
— Data movement via dual-address transfers for 8-, 16-, 32-, and 128-bit data values
— Programmable source and destination addresses, transfer size, and support for enhanced
address modes
— Support for major and minor nested counters with one request and one interrupt per channel
— Support for channel-to-channel linking and scatter/gather for continuous transfers with fixed
priority and round-robin channel arbitration
— External request pins for up to four channels
• FlexBus (external interface)
— Glueless connections to 8-, 16-, or 32-bit external memory devices (SRAM, Flash, ROM, etc.)
— Support for independent primary and secondary wait states per chip select
