# pinLengthBitOffset

The offset, in bits, within the PIN block to mark a location for filling in the PIN length, which is always left justified. 0 by default.

## Declaration

```swift
var pinLengthBitOffset: Int { get set }
```

## Discussion

Discussion The value of PINLengthBitOffset indirectly controls the internal system units indicator. If PINLengthBitOffset is byte aligned (that is, PINLengthBitOffset % 8 == 0), the internal representation of PINLengthBitOffset gets converted from bits to bytes.
