+ * from the order that the CON and DAT registers are set in.
+ *
+ * The three states the pin can be are {IN,OUT,SFN} which gives us 9
+ * combinations of changes to check. Three of these, if the pin stays
+ * in the same configuration can be discounted. This leaves us with
+ * the following:
+ *
+ * { IN => OUT }  Change DAT first
+ * { IN => SFN }  Change CON first
+ * { OUT => SFN } Change CON first, so new data will not glitch
+ * { OUT => IN }  Change CON first, so new data will not glitch
+ * { SFN => IN }  Change CON first
+ * { SFN => OUT } Change DAT first, so new data will not glitch [1]
+ *
+ * We do not currently deal with the UP registers as these control
+ * weak resistors, so a small delay in change should not need to bring
+ * these into the calculations.
+ *
+ * [1] this assumes that writing to a pin DAT whilst in SFN will set the

- *
- * The three states the pin can be are {IN,OUT,SFN} which gives us 9

- * in the same configuration can be discounted. This leaves us with
- * the following:
- *
- * { IN => OUT }  Change DAT first
- * { IN => SFN }  Change CON first
- * { OUT => SFN } Change CON first, so new data will not glitch
- * { OUT => IN }  Change CON first, so new data will not glitch
- * { SFN => IN }  Change CON first
- * { SFN => OUT } Change DAT first, so new data will not glitch [1]
- *
- * We do not currently deal with the UP registers as these control
- * weak resistors, so a small delay in change should not need to bring

- *
- * [1] this assumes that writing to a pin DAT whilst in SFN will set the
