Notes

47.CE0 = OE = ADS = CNTEN = BE0 – BE1 = LOW; CE1 = CNTRST = MRST = CNT/MSK = HIGH.

48.This timing is valid when one port is writing, and other port is reading the same location at the same time. If tCCS is violated, indeterminate data is Read out.

49.If tCCS < minimum specified value, then R_Port is Read the most recent data (written by L_Port) only (2 * tCYC2 + tCD2) after the rising edge of R_Port's clock. If tCCS > minimum specified value, then R_Port is Read the most recent data (written by L_Port) (tCYC2 + tCD2) after the rising edge of R_Port's clock.
