CCLK cycle.

a write to a read, or vice-versa. This action causes the cur-

and WRITE is High. Similarly, while WRITE is High, no
more that one CS should be asserted.

an abort, data is assumed to be unaligned to word bound-

write), the data is not accepted. Acceptance instead
occurs on the first clock after BUSY goes Low, and the
data must be held until this has happened.
