Detailed Description
ALT0
External clock input for ARM clock.
ALT6
ALT4
ALT2
External peripheral clock source.
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.
ALT0
ALT1
ALT1
ALT6
Clock-out pin from CCM, clock source is controllable
and can also be used for debug.
PMIC power-ready signal, which can be configured
either from GPIO1_0 or TX1.
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.
