At the third rising edge of CLKA, the T
BCCS
parameter is
violated with two writes to memory location 0x0F. The DOA
and DOB busses reflect the contents of the DIA and DIB
busses, but the stored value at 0x0F is invalid.
At the fourth rising edge of CLKA, a read operation is per-
formed at memory location 0x0F and invalid data is present
on the DOA bus. Port B also executes a read operation to
memory location 0x0F and also reads invalid data.
At the fifth rising edge of CLKA a read operation is per-
formed that does not violate the T
BCCS
parameter to the
previous write of 0x7E by Port B. THe DOA bus reflects the
recently written value by Port B.
