Level translator feature

Figure 7.

Level translator feature

When enabled, the GPIO 0-7 bits are internally mapped to GPIO 8-15 bits. The

STMPE1601 becomes an 8-channel level translator where each of the channels may have

its direction set individually. As GPIO 0-7 operates from Vcc, and GPIO 8-15 operates from

Vio, this allows the 2 groups of GPIO to work as a level translator.

Warning:

When the level translator feature is enabled, the “Set pin”,

“Clear pin” and “Set direction” bits in the corresponding

registers will be ignored. However, the “Monitor pin”, “Edge

detect”, “Pull-up” features are still available in the GPIOs

used as level translator.
