Constructor is setting a digital pin before setting OUTPUT mode.

In the constructor 
`Adafruit_TFTLCD::Adafruit_TFTLCD(uint8_t cs, uint8_t cd, uint8_t wr, uint8_t rd, uint8_t reset)`

we see the following lines of code:

```
  if (reset) {
    digitalWrite(reset, HIGH);
    pinMode(reset, OUTPUT);
  }
```

Is it valid to be setting the line to HIGH before the pinMode is set?  On SAMD51 the default pin mode is INPUT_PULLUP.
