##-- description:
##-- This file contains the pin definitions for the CONV-TTL-BLO FPGA. The pin
##-- names reflect those of net names at the schematic level. To keep to CERN
##-- coding standards (http://www.ohwr.org/documents/24) and make the code more
##-- readable, the pin names have been lowercased and the pin type is indicated
##-- by its suffix. The suffix "_i" indicates an input pin, "_o" an output pin
##-- and "_b" a bidirectional pin.
##--
##-- An example of net name change is given below:
##-- LED_WR_OWNADDR_I2C -> led_wr_ownaddr_i2c_o
##--
##-- Apart from this, some pins have been renamed completely and do not resemble
##-- the schematics. These pins are:
##-- TTL/INV_TTL_N -> ttl_switch_n_i
