4 Peripherals
The integrated peripherals of the 280x are described in the following subsections:
• Three 32-bit CPU-Timers
• Up to six enhanced PWM modules (ePWM1, ePWM2, ePWM3, ePWM4, ePWM5, ePWM6)
• Up to four enhanced capture modules (eCAP1, eCAP2, eCAP3, eCAP4)
• Up to two enhanced QEP modules (eQEP1, eQEP2)
• Enhanced analog-to-digital converter (ADC) module
• Up to two enhanced controller area network (eCAN) modules (eCAN-A, eCAN-B)
• Up to two serial communications interface modules (SCI-A, SCI-B)
• Up to four serial peripheral interface (SPI) modules (SPI-A, SPI-B, SPI-C, SPI-D)
• Inter-integrated circuit module (I2C)
• Digital I/O and shared pin functions
4.1 32-Bit CPU-Timers 0/1/2
There are three 32-bit CPU-timers on the 280x devices (CPU-TIMER0/1/2).
CPU-Timer 0 and CPU-Timer 1 can be used in user applications. Timer 2 is reserved for DSP/BIOS™.
These timers are different from the timers that are present in the ePWM modules.
NOTE
If the application is not using DSP/BIOS, then CPU-Timer 2 can be used in the application.
