Power Dissipation

Power Dissipation
Table 5 provides information on power dissipation. The modes are 1:1, where CPU and bus speeds are
equal, and 2:1, where CPU frequency is twice bus speed.
NOTE
The values in Table 5 represent VDDL-based power dissipation and do not
include I/O power dissipation over VDDH. I/O power dissipation varies
widely by application due to buffer current, depending on external circuitry.
The VDDSYN power dissipation is negligible.
