index URL

Address of the peripheral's control register

XDCscript usage meta-domain
var params = new CS.Params;
  ...
params.baseAddr = UInt undefined;
 
DETAILS
A peripheral's registers are commonly accessed through a structure that defines the offsets of a particular register from the lowest address mapped to a peripheral. That lowest address is specified by this parameter.
