## Purpose:     Architecture definitions.

## Description: This file contains various definitions and macros that are

##              useful for writing assembly code for the CalmRISC16 CPU family.

## Usage:

##              #include

## CalmRISC16 thread and interrupt saved state. This must match the layout of

## the HAL_SavedRegisters in hal_arch.h. Do not change this without changing

## the layout there, or viceversa.

##-----------------------------------------------------------------------------

## CPU specific macros. These provide a common assembler interface to

## operations that may have CPU specific implementations on different

## variants of the architecture.
