defined differently for supervisor and user privilege modes. By
convention, in both modes R15 serves as the link register for subroutine
calls. R0 is typically used as stack pointer.
The user programming model consists of 16 general-purpose 32-bit
registers (R[15:0]), the 32-bit PC, and the C bit. The C bit is implemented
as bit 0 of the processor status register (PSR) and is the only portion of
the PSR accessible in the user model.
