User manual
3.4.9 Power Control for Peripherals register (PCONP - 0xE01F C0C4)
The PCONP register allows turning off selected peripheral functions for the purpose of
saving power. This is accomplished by gating off the clock source to the specified
peripheral blocks. A few peripheral functions cannot be turned off (i.e. the Watchdog timer,
GPIO, the Pin Connect block, and the System Control block).
Some peripherals, particularly those that include analog functions, may consume power
that is not clock dependent. These peripherals may contain a separate disable control that
turns off additional circuitry to reduce power. Information on peripheral specific power
saving features may be found in the chapter describing that peripheral.
Each bit in PCONP controls one peripheral as shown in
correspond to the related peripheral number as shown in the APB peripheral map
2–17 “APB peripherals and base addresses”
chapter.
If a peripheral control bit is 1, that peripheral is enabled. If a peripheral bit is 0, that
peripheral’s clock is disabled (gated off) to conserve power. For example if bit 19 is 1, the
I
Important: valid read from a peripheral register and valid write to a peripheral
register is possible only if that peripheral is enabled in the PCONP register!
