    4347Notes
    4448=====
    45 
    46 Based on papyrus bsp which only really supports
    47 the PowerOpen ABI with an ELF assembler.
    48 
    49 Need to Modify external_exception_ISR with correct code to read the vector,
    50 and to clear the interrupt.
     49The console and real-time clock drivers use the libchip library.
