Reserved signals should be disconnected for compatibility with future revisions of the device.
For signals with same functionality in all modes the appropriate cells are empty.
The choice between GPIO function and other function is by GPIO registers setup. For configuration details, see Chapter 23,
GPIO in the MSC8144 Reference Manual .
Open-drain signal.
Internal 20 K Ω pull-up resistor.
For signals with GPIO functionality, the open-drain and internal 20 K Ω pull-up resistor can be configured by GPIO register
programming. See Chapter 23 , GPIO of the MSC8144 Reference Manual for configuration details.
