Code

xxx_MODE were used as if they were port bits, not registers.

- fw/atspi/atspi.c (init_io): comment had the wrong initial value for SCLK
- fw/atspi/atspi.c (init_io): xxx_MODE are registers, not bits ...
- fw/common/io.h (IRQ_RF), fw/atspi/atspi.c (init_io): indicate pending
  moving of IRQ_RF
