Dynamic Power Management Controller
The Dynamic Power Management Controller (DPMC) works in conjunc-
tion with the PLL, allowing the user to control the processor's
performance characteristics and power dissipation dynamically. The
DPMC provides these features that allow the user to control performance
and power:
• Multiple operating modes – The processor works in four operating
modes, each with different performance characteristics and power
dissipation profiles. See
• Peripheral clocks – Clocks to each peripheral are disabled automat-
ically when the peripheral is disabled.
• Voltage control – The processor provides an on-chip switching reg-
ulator controller which, with some external components, can
generate internal voltage levels from the external Vdd (V
supply.
Depending on the needs of the system, the voltage level can be
reduced to save power. See
