— 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
— 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
Software watchdog timer
— 32-bit counter
— Low-power mode support
Clock generation features
— One to 10 MHz crystal, 8 MHz on-chip trimmed relaxation oscillator, or external oscillator reference options
— Two to 10 MHz reference frequency for normal PLL mode
— System can be clocked from PLL or directly from crystal oscillator or relaxation oscillator
— Low power modes supported
— 2
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)
— 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:
(PWM counter reaches zero) or when the channel is disabled.
burst transfers
– Power-on reset (POR)
– External
– Software
– Watchdog
– Loss of clock
n
(n ≤ 0 ≤ 15) low-power divider for extremely low frequency operation
