Registers
Each cog contains 16 special purpose registers for accessing I/O pins, the built-in counters
and video generator, and the parameter passed at the moment the cog is launched. All of
these registers are explained in the Spin Language Reference and most of the information
applies to both Spin and Propeller Assembly. The following table illustrates the 16 special
purpose registers, indicates where to find information and what details, if any, do not apply to
Propeller Assembly.
Each of these registers can be accessed just like any other register in the Destination or
Source fields of instructions, except for those that are designated “(Read-Only).” Read-only
registers can only be used in the Source field of an instruction.
