+ * m68hc11_sim.c (cpu_move8): Call sim_engine_abort in default case.
+ (cpu_move16): Likewise.
+ (sim_memory_error): Use sim_io_printf.
+ (cpu_option_handler): Fix compilation warning.
+ * interp.c (sim_hw_configure): Fix compilation warning;
+ remove m68hc12sio@2 device.
+ (sim_open): Likewise.
+ * dv-m68hc11tim.c (m68hc11tim_port_event): Fix clear of TFLG2
+ flags when reset.
+ (cycle_to_string): Improve convertion of cpu cycle number.
+ (m68hc11tim_info): Print info about PACNT.
+ (m68hc11tim_io_write_buffer): Fix clearing of TFLG2; handle
+ TCTL1 and TCTL2 registers.
+ * dv-m68hc11.c (m68hc11_info): Print 6811 current running mode.

* interp.c (sim_hw_configure): Save the HW cpu pointer in the
cpu struct.
(sim_hw_configure): Connect the capture input/output events.
