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
V
Table 8.
Power measurements in Active, Sleep, and Deep-sleep modes were performed under the
following conditions (see LPC122x user manual):

PLL (PLL output
frequency = 24 MHz)
WDosc (WDosc output
frequency = 500 kHz)

Active mode: all GPIO pins set to input with external pull-up resistors.
Sleep and Deep-sleep modes: all GPIO pins set to output driving LOW.
Deep power-down mode: all GPIO pins set to input with external pull-up resistors.
