+### PinGen
+
+pinfunctions.py contains the "pinspec" list containing the Python functions
+which generate the necessary signals for gpio, uart, i2c, etc. (with IOType
+information). PinGen class uses "__call__" and "pinspec" to effectively create a
+Lambda function for generating specified peripheral signals.

 ## The GPIO block 
 
 *NOTE !* - Need to change 'bank' terminology for the GPIO block in doc and code!
