Left_Port (L_Port) Write to Right_Port (R_Port) Read
[38, 39, 40]
Notes:
38. CE
= OE = ADS = CNTEN = B0 – B3 = LOW; CE
= CNTRST = MRST = CNT/MSK = HIGH.
39. This timing is valid when one port is writing, and other port is reading the same location at the same time. If t
CCS
is violated, indeterminate data will be Read out.
40. If t
CCS
< minimum specified value, then R_Port will Read the most recent data (written by L_Port) only (2 * t
CYC2
+ t
) after the rising edge of R_Port's clock.
If t
CCS
> minimum specified value, then R_Port will Read the most recent data (written by L_Port) (t
CYC2
+ t
CD2
) after the rising edge of R_Port's clock.
