Table 32. Write Timing
Note: 1. Any input used to select an internal DSM function.
2. Assuming data is stable before active write signal.
3. Assuming write is active before data becomes valid.
4. TWHAX2 is the address hold time for DPLD inputs that are used to generate Sector Select signals for internal DSM memory.
