    unhandled HW access : R32 0xCC006844 (pc:0x80078BE8)
    unhandled HW access : R32 0xCC006858 (pc:0x80078BFC)
    Probably source code typo.

    on 0x80096080 (clear buffer?) with parameters :
        r3 = 0x8071A2E0
        r4 = 0
        r5 = 0x900040 (9*1024*1024 + 64)
    Unexpected DEC exception can be generated, when CPU decrementing DEC 
    register every opcode. Can be fixed, by decrementing DEC, e.g. every 12
    opcodes.
