Objective data sheet
10.1 Peripheral power consumption
10.2 Power consumption
The supply current per peripheral is measured as the difference in supply current between
the peripheral block enabled and the peripheral block disabled in the SYSAHBCLKCFG
and PDRUNCFG (for analog blocks) registers. All other blocks are disabled in both
registers and no code is executed. Measured on a typical sample at T
noted otherwise, the system oscillator and PLL are running in both measurements.
The supply currents are shown for system clock frequencies of <tbd>.
Table 8.
Power measurements in Active, Sleep, and Deep-sleep modes were performed under the
following conditions (see LPC122x user manual):
