Most of the peripheral signals are multiplexed with general-purpose input/output (GPIO) signals. This
enables the user to use a pin as GPIO if the peripheral signal or function is not used. On reset, GPIO pins
are configured as inputs. The user can individually program each pin for GPIO mode or peripheral signal
mode. For specific inputs, the user can also select the number of input qualification cycles. This is to filter
unwanted noise glitches. The GPIO signals can also be used to bring the device out of specific low-power
modes.
CPU-Timers 0, 1, and 2 are identical 32-bit timers with presettable periods and with 16-bit clock
prescaling. The timers have a 32-bit count down register, which generates an interrupt when the counter
reaches zero. The counter is decremented at the CPU clock speed divided by the prescale value setting.
When the counter reaches zero, it is automatically reloaded with a 32-bit period value. CPU-Timer 2 is
reserved for Real-Time OS (RTOS)/BIOS applications. CPU-Timer 1 is also reserved for TI system
functions. CPU-Timer 2 is connected to INT14 of the CPU. CPU-Timer 1 can be connected to INT13 of
the CPU. CPU-Timer 0 is for general use and is connected to the PIE block.
The 280x devices support the following peripherals which are used for embedded control and
communication:
ePWM:
The enhanced PWM peripheral supports independent/complementary PWM generation,
adjustable dead-band generation for leading/trailing edges, latched/cycle-by-cycle trip
mechanism. Some of the PWM pins support HRPWM features.
The enhanced capture peripheral uses a 32-bit time base and registers up to four
programmable events in continuous/one-shot capture modes.
This peripheral can also be configured to generate an auxiliary PWM signal.
