Figure 78. Input to Output Disable / Enable
Table 121. CPLD Combinatorial Timing (5V Devices)
Note: 1. Fast Slew Rate output available on PA3-PA0, PB3-PB0, and PD2-PD1. Decrement times by given amount
2. tPD for MCU address and control signals refers to delay from pins on Port 0, Port 2, RD WR, PSEN and ALE to CPLD combinatorial
output (80-pin package only)
