6.6 System Control

This section describes the 280x oscillator, PLL and clocking mechanisms, the watchdog function and the low power modes. Figure 6-25 shows the various clock and reset domains in the 280x devices that will be discussed.

TMS320F2809 TMS320F2808 TMS320F2806 TMS320F2802 TMS320F2801 TMS320C2802 TMS320C2801 TMS320F28016 TMS320F28015 clkres_prs230.gif
A. CLKIN is the clock into the CPU. It is passed out of the CPU as SYSCLKOUT (that is, CLKIN is the same frequency as SYSCLKOUT).
Figure 6-25 Clock and Reset Domains

The PLL, clocking, watchdog and low-power modes, are controlled by the registers listed in Table 6-31.
