7
— Unused analog channels can be used as digital I/O
Four 32-bit timers with DMA support
— 12.5 ns resolution at 80 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 output compare
— DMA trigger capability on input capture or output compare
Four-channel general purpose timer
— 16-bit architecture
— Programmable prescaler
— Output pulse-widths variable from microseconds to seconds
— Single 16-bit input pulse accumulator
— Toggle-on-overflow feature for pulse-width modulator (PWM) generation
— One dual-mode pulse accumulation channel
Pulse-width modulation timer
— Support for PCM mode (resulting in superior signal quality compared to conventional PWM)
— Operates as eight channels with 8-bit resolution or four channels with 16-bit resolution
— Programmable period and duty cycle
— Programmable enable/disable for each channel
— Software selectable polarity for each channel
— Period and duty cycle are double buffered. Change takes effect when the end of the current period is reached
(PWM counter reaches zero) or when the channel is disabled.
— Programmable center or left aligned outputs on individual channels
— Four clock sources (A, B, SA, and SB) provide for a wide range of frequencies
— Emergency shutdown
Two periodic interrupt timers (PITs)
— 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
— Standby power supply (Vstby) keeps the RTC running when the system is shut down
Software watchdog timer
— 32-bit counter
— Low-power mode support
Backup watchdog timer (BWT)
— Independent timer that can be used to help software recover from runaway code
— 16-bit counter
— Low-power mode support
Clock generation features
— Crystal, on-chip trimmed relaxation oscillator, or external oscillator reference options
— Trimmed relaxation oscillator
