GPIO controller STMPE811
52/65 Doc ID 14489 Rev 6
GPIO_CLR_PIN Clear pin state register
Address: 0x11
Type: R/W
Reset: 0x00
Description: GPIO clear pin state register.
Writing ‘1’ to this bit causes the corresponding GPIO to go to 0 state.
Writing ‘0’ has no effect.
GPIO_MP_STA GPIO monitor pin state register
Address: 0x12
Type: R/W
Reset: 0x00
Description: GPIO monitor pin state.
Reading this bit yields the current state of the bit. Writing has no effect.
GPIO_DIR GPIO set pin direction
Address: 0x13
Type: R/W
Reset: 0x00
Description: GPIO set pin direction register.
Writing ‘0’ sets the corresponding GPIO to input state, and ‘1’ sets it to output state.
All bits are ‘0’ on reset.
GPIO_ED_STA GPIO edge detect status
Address: 0x14
Type: R/W
Reset: 0x00
Description: GPIO edge detect status register. An edge transition has been detected.
