These macros are defined in errors.lib:
A.5 Rabbit Registers
Macros are defined for all of the Rabbit registers that are accessible for application programming. A list of
these register macros can be found in the user’s manuals for the Rabbit microprocessor, as well as in the
Rabbit Registers file accessible from the Dynamic C Help menu.
A.5.1 Shadow Registers
Shadow registers exist for many of the I/O registers. They are character variables defined in the BIOS. The
naming convention for shadow registers is to append the word Shadow to the name of the register. For
example, the global control status register, GCSR, has a corresponding shadow register named
GCSRShadow.
The purpose of the shadow registers is to allow the program to reference the last value programmed to the
actual register. This is needed because a number of the registers are write only.
