STMPE321

GPIO controller

Doc ID 15791 Rev 3

23/40

The function of each bit is shown inTable 9:

Table 9.

GPIO control bits function

Function

GPIO monitor pin state

Reading this bit yields the current state of the bit. Writing has no

effect.

GPIO set pin state

Writing '1' to this bit causes the corresponding GPIO to go to '1' state

Writing '0' to this bit causes the corresponding GPIO to go to '0' state

GPIO set pin direction

'0' sets the corresponding GPIO to input state, and '1' sets it to output

state. All bits are '0' on reset.

GPIO function

'1' sets the corresponding GPIO to function as GPIO, and '0' sets it to

touchkey mode.
