Detailed Description

External ARM Clock

EXT_ARMCLK

ALT0

External clock input for ARM clock.

External Peripheral Clock

I2C1_CLK

ALT6

External peripheral clock source.

External 32-kHz Clock

CAPTURE

ALT4

External clock input of 32 kHz, used when the internal

24M Oscillator is powered off, which could be

configured either from CAPTURE or CSPI1_SS1.

CSPI1_SS1

ALT2

Clock Out

CLKO

ALT0

Clock-out pin from CCM, clock source is controllable

and can also be used for debug.

Power Ready

GPIO1_0

ALT1

PMIC power-ready signal, which can be configured

either from GPIO1_0 or TX1.

TX1

ALT1

Tamper Detect

GPIO1_1

ALT6

Tamper-detect logic is used to issue a security

violation. This logic is activated if the tamper-detect

input is asserted. Tamper-detect logic is enabled by the

bit of IOMUXC_GPRA[2]. After enabling the logic, it is

impossible to disable it until the next reset.
