This MCA pin is connected to the gate of an N-channel
MOSFET. A 10K pull-down resistor is connected to GND
on this signal too. The drain of the MOSFET is
connected to ConnectCore 6 Plus signal ON/OFF (pad
D18). The source of the MOSFET is connected to GND.
This signal is reserved on the module and allows MCA
to control ON/OFF signal over software.

KINETIS_32K
This MCA pin is connected to 32K output of the PMIC.
It’s the clock input of the MCA processor.

AC21 MCA_IO28
Not used on module.
For K10 and K20 processors, this pin is VBAT.
ConnectCore 6 Plus SOM has a 0R resistor foreseen on
this pin for connecting this signal to LDO3_MCA. By
default, the resistor is not populated and MCA_IO28 is
available on module pad.
1x 100 nF + 1x1 µF capacitors connected to GND are
placed close to this pin on ConnectCore 6 Plus SOM.
