Power supply
The STMPE1600 operates with a single power supply VCC that ranges from 1.65V to 3.6V.
The GPIO remains valid until the V
reset.
Reset
The STMPE1600 is equipped with an internal POR circuit that holds the device in reset
state, until the V
In the duration when reset pin is asserted, all GPIO are reset and default to input states.

Polarity inversion register.
This register allows the user to invert the polarity of the input port register data. If a bit
in this register is set (written with ‘1’), the Input Port Data polarity is inverted. If a bit in
this register is cleared (written with a ‘0’), the Input Port Data polarity is retained. This
is for Active HIGH or Active LOW operation register. The polarity of the read register
can be inverted with this register.
Writing a ‘1’ to the PINV[x] bit will enable polarity inversion on the Input Port. Writing a ‘0’, the
input port polarity is retained. The reset value is 0.
