10. TIMING CHARACTERISTICS
(1) System path read/write characteristics 1 (80 system MPU)
Table 10.1
*1. This is in case of making the access by WR and RD, setting the CS = LOW.
*2. This is in case of making the access by CS, setting the WR, RD = LOW.
*3. Input signal rise and fall time (tr, tf) must not exceed 15 ns. When the system cycle time is used at a high speed,
*4. Timing is entirely specified with reference to 20% or 80% of V
