NuMicro™ NUC100 Series Medium Density has up to 80 General Purpose I/O pins can be shared
with other function pins; it depends on the chip configuration. These 80 pins are arranged in 5
ports named with GPIOA, GPIOB, GPIOC, GPIOD and GPIOE. Each port equips maximum 16
pins. Each one of the 80 pins is independent and has the corresponding register bits to control the
pin mode function and data.
NuMicro™ NUC100 Series Low Density has up to 65 General Purpose I/O pins can be shared
with other function pins; it depends on the chip configuration and package. These 65 pins are
arranged in 4 ports named with GPIOA, GPIOB, GPIOC and GPIOD with each port equips
maximum 16 pins and another port named GPIOE with 1 pins PE.5.
The I/O type of each of I/O pins can be configured by software individually as input, output, open-
drain or quasi-bidirectional mode. After reset, the I/O type of all pins stay in quasi-bidirectional
mode and port data register GPIOx_DOUT[15:0] resets to 0x0000_FFFF. Each I/O pin equips a
very weakly individual pull-up resistor which is about 110KΩ~300KΩ for V
