4 Peripherals
The integrated peripherals of the F2812 are described in the following subsections:
• Three 32-bit CPU-Timers
• Two event-manager modules (EVA, EVB)
• Enhanced analog-to-digital converter (ADC) module
• Enhanced controller area network (eCAN) module
• Multichannel buffered serial port (McBSP) module
• Serial communications interface modules (SCI-A, SCI-B)
• Serial peripheral interface (SPI) module
• 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 F2812 devices (CPU-TIMER0/1/2).
CPU-Timers 1 and 2 are reserved for the real-time OS (such as DSP/BIOS). CPU-Timer 0 can be used in
user applications. These timers are different from the general-purpose (GP) timers that are present in the
Event Manager modules (EVA, EVB).
NOTE
If the application is not using DSP/BIOS, then CPU-Timers 1 and 2 can be used in the
application.
