Bus Operation
7-30
recognized asserted, the processor ignores the data and appends a wait state instead of
terminating the transfer. The processor continues to sample TA on successive rising edg-
es of BCLK until TA is recognized as asserted. The registered data is then passed to the
appropriate memory unit. If more than one read cycle is required to read in the operand(s),
C1 and C2 are repeated accordingly.
NOTE: It is assumed that the acknowledge termination ignore state capability is disabled.
