    230  * According to TECH I vol. 14 (CQ Publishing, Tokyo, 2002) p. 184,
    231  * byte-access to area 6 becomes word-access if preceding access is
    232  * word-wise. Inserting a dummy byte-access works around the problem.
    233  * Area 5 is not affected by this bug.
    234  *
    235  * Therefore, we insert a dummy byte-wise read to HD64461_PCC0_MEMBASE
    236  * before any byte-access to area 6 (channel 0).
    237  *
    238  * Note that we used to use HD64461_PCC0_IOBASE for this purpose. But,
    239  * read access to that register can modify device states, which breaks
    240  * ep(4) at least. On the other hand, since HD64461_PCC0_MEMBASE is
    241  * assigned to attribute memory, read access should be harmless.
