    /**
     * The AVR GDB client (avr-gdb) defines a set of parameters relating to AVR targets. These parameters are
     * hardcoded in the AVR GDB source code. The client expects all compatible GDB RSP servers to be aware of
     * these parameters.
     *
     * An example of these hardcoded parameters is target registers and the order in which they are supplied; AVR GDB
     * clients expect 35 registers to be accessible via the server. 32 of these registers are general purpose CPU
     * registers. The GP registers are expected to be followed by the status register (SREG), stack pointer
     * register (SPH & SPL) and the program counter. These must all be given in a specific order, which is
     * pre-determined by the AVR GDB client. See AvrGdbRsp::getRegisterNumberToDescriptorMapping() for more.
     *
     * For more on this, see the AVR GDB source code at https://github.com/bminor/binutils-gdb/blob/master/gdb/avr-tdep.c
     *
     * The AvrGdpRsp class extends the generic GDB RSP debug server and implements these AVR specific parameters.
