2. Through the distributed control registers in the specific peripheral that shares it pins with the standard GPIO
functionality.
The Global I/O registers offer full control of:
1. Configuring each pin as a GPIO.
2. Setting each pin as input or output.
3. Reading the pin’s logic state, if it is configured as an input pin.
4. Setting the logic state of the pin, if it is configured as an output pin.
5. Configuring pin/pins as open drain or push-pull (Normal)
The Global I/O registers include Global I/O EN register, Global I/O OE Register, Global I/O Open Drain Control
Register, Global I/O Value Register and Global I/O Read Register.
The following is showing the format of Global I/O EN Register (GLBIOEN) as an example:
BIT NUMBER
29:0
Bit Name
GLOBAL_IO_EN
Access
R/W
Default
00_0000_0000_0000_0000_0000_0000_0000
Bits 29-0: GLOBAL_IO_EN – This register enables the global control of digital I/O pins
0 = Control of IO is done by the functional block assigned to the IO (Default)
1 = Control of IO is done by Global IO registers.
