@ -42,7 +42,7 @@ Other pinouts can be used by passing a `pinout` parameter to the `init`
function.
This pinout consists of 4 numbers giving the *positive* pin in each differential pair, in the order CK, D0, D1, D2, D3, using GPIO numbering.
The default pinout is written `{13, 15, 17, 19}`.
Only pin numbers from 12 to 20 are valid, as other pins are not connected to the HSTX peripheral.
Only pin numbers from 12 to 19 are valid, as other pins are not connected to the HSTX peripheral.
Using invalid pin numbers is an undignosed error.
