SPRS230F–OCTOBER 2003–REVISED SEPTEMBER 2005
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 (I

C)
Digital I/O and shared pin functions
There are three 32-bit CPU-timers on the 280x devices (CPU-TIMER0/1/2).
CPU-Timer 1 is reserved for TI system functions and Timer 2 is reserved for DSP/BIOS. CPU-Timer 0
can be used in user applications. These timers are different from the timers that are present in the ePWM
modules.
NOTE
NOTE: If the application is not using DSP/BIOS, then CPU-Timer 2 can be used in the
application.
Figure 4-1. CPU-Timers
In the 280x devices, the timer interrupt signals (TINT0, TINT1, TINT2) are connected as shown in
Figure 4-2
