 ## PARAMETERS
 
 ### CFGW
-The `CFGW` parameter defines the width of the configuration bus of the io cell. IO cells generally include a set of configuration inputs for things like drive strength and operating modes. Setting `CFGW` to a large value (eg. 16/32) should have zero impact on the design as the extra bus bits get optimized away during implementation.
+The `CFGW` parameter defines the width of the configuration bus of the io cell. IO cells generally include a set of configuration inputs for things like drive strength and operating modes. Setting `CFGW` to a large value (eg. 16/32) should have zero impact on the design as the extra bus bits get optimized away during implementation. The connection between the generic `CFG` bus and the technology specific IO cell is done within the techology specific cell wrapper library.
 
 For la_bidir, the first 8 bits of the configuration bus are reserved for the functionality shown in the table below.

 ### {NO,EA,WE,SO}CELLMAP
 Specifies the type of cells, pin connections, properties, and power connections of all cells in the padring with the exception of filler cells. The physical placement of the cells within the padring shall be done in the order dictated by `CELLMAP`. The CELLMAP is a vector of size NCELLS * 40, with the 40bit vector split into the following fields:
 
-  * PIN[7:0]     = CELLMAP[7:0]   = pin number connected to cell
-  * COMP[7:0]    = CELLMAP[15:8]  = pin number for complementary pad for differential cells
+  * PIN[7:0]     = CELLMAP[7:0]   = pin number connected to cell. Positive signal in case of differential pairs.
+  * COMP[7:0]    = CELLMAP[15:8]  = pin number of complementary (negative) pad to `PIN`. Used for differential IO cells.
   * TYPE[7:0]    = CELLMAP[23:16] = cell type (see ./la_padring.vh)
   * SECTION[7:0] = CELLMAP[31:24] = padring power section number connected to cell
   * PROP[7:0]    = CELLMAP[39:32] = property passed to technology specific iolib implementation
