NXP Semiconductors
32-bit ARM Cortex-M4 microcontroller
registers. All other blocks are disabled and no code accessing the peripheral is executed.
The supply currents are shown for system clock frequencies of 12 MHz, 48 MHz, 96 MHz
and 180MHz.

[1] The supply current per peripheral is measured as the difference in supply current between the peripheral
block enabled and the peripheral block disabled using PDRUNCFG0/1 registers. All other blocks are
disabled and no code accessing the peripheral is executed.
[2] Typical ratings are not guaranteed. Characterized through bench measurements using typical samples.
