+ * { 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

- *
- * 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

- *
