MSPM0C1104: GPIO setting in configuration

Please let us know pull up value as well as series resistance value to connect the transistor base  at GPIO A24 to MCU 

In ODIO mode, pull-up resistors affect signal rise time.

A larger resistor supports slower signal speeds.
A smaller resistor consumes more power.
Typically, a 2.2kΩ pull-up resistor connected to 3.3V is sufficient to support 1MHz signal transmission.

The series resistance depends on your PCB layout and EMC requirements.

In short, the values ​​is entirely determined by your needs.

Also please let us know configuration setting " Any"/"Open Drain" shall be effective.

ODIO type IO support hardware open drain mode.

SDIO with Hi-Z enable, also supports open drain mode.

pin can source 20 mA /6mA as per datasheet .

Yes, with different type of IO, the supported current is also different.
