GPIO Drive Strength 0 Select
The output drive strength supports four modes. The mode selection is set using the
combination of the GPIO0_DS1_SEL and GPIO0_DS0_SEL bits for the associated GPIO
pin. Refer to the GPIO Drive Strength section, above, for the selection options on these
I/O pins.
Refer to the symbols V
OL_GPIO
and V
OH_GPIO
in the MAX32660 Data Sheet Electrical
Characteristics table for details of the drive strengths for these I/O pins.

C as an
alternate function only support two drive strength options.
0: Low output drive strength selected.
1: High output drive strength selected.
Refer to V
OL_I2C
and V
OH_I2C
in the MAX32660 Data Sheet Electrical Characteristics table
for details of the drive strengths for these I/O pins.
