/* One PCA9655E I/O expander port connected to matrix rows.
write() can output logiclevel to strobePin, one LED pin, or multiple pins.

Instantiation
 ------------
Example instantiation:
    const uint8_t PortIOE::DEVICE_ADDR = 0x20;      //PCA9655E address, all 3 ADDR pins are grounded
    PortIOE port0(0);
    PortWrite_PCA9655E rowPort0(port0);

Diode orientation
 ----------------
Diode orientation is explained in keybrd_library_user_guide.md > Diode orientation
