READ/WRITE TIMING FOR THE 68-PORT MPU
(Ta=25℃, VDD=0V, VSS=-5V)
Note:
1. tCYC6 indicates the cycle during which CS/E are high; it does not indicate are cycle of the E signal.
CONTROL TIMING FOR 80-PORT/68-PORT MPU
(Ta=25℃, VDD=0V, VSS=-5V)
Note:
1. The input timing of the FR delay time is determined by the PT6520 (Slave)
2. The output timing of the FR delay time is determined by the PT6520 (Master)
