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

4.132-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.
