STMPE1208S
Register map and function description
25/51
GPIO_STA_L
GPIO state register L
Address:
0x1E
Type:
R/W
Reset:
0x00
Description:
If a DIO is set to function as GPIO (GPIO_CFG register) and output (GPIO_DIR
register), the bits in this register would determine the output value of the
corresponding GPIO. Applicable for GPIOs 0 - 7.
GPIO_STA_H
GPIO state register H
Address:
0x1F
Type:
R/W
Reset:
0x00
Description:
If a DIO is set to function as GPIO (GPIO_CFG register) and output (GPIO_DIR
register), the bits in this register would determine the output value of the
corresponding GPIO. Applicable for GPIOs 8 - 11.
GPIO_CFG_L
GPIO configuration register
Address:
0x20
Type:
R/W
Reset:
0x00
Description:
Writing ‘1’ in this GPIO configuration register sets the corresponding DIO as GPIO.
Applicable for GPIOs 0-7.
GPIO_CFG_H
GPIO configuration register
Address:
0x21
Type:
R/W
Reset:
0x00
Description:
Writing ‘1’ in this GPIO configuration register sets the corresponding DIO as GPIO.
Applicable for GPIOs 8-11.
