DS21929D-page 13 93XX46X/56X/66X/76X/86X 3.6 ERASE/WRITE DISABLE And ENABLE (EWDS/EWEN) The 93XX series devices power-up in the Erase/Write Disable (EWDS) state. All programming modes must be preceded by an Erase/Write Enable (EWEN) instruc- tion. Once the EWEN instruction is executed, program- ming remains enabled until an EWDS instruction is executed or VCC is removed from the device. To protect against accidental data disturbance, the EWDS instruction can be used to disable all Erase/Write functions and should follow all programming operations. Execution of a READ instruction is independent of both the EWEN and EWDS instructions. FIGURE 3-5: EWDS TIMING FIGURE 3-6: EWEN TIMING CS CLK DI 10 00 0 x ••• x TCSL 1x CS CLK DI 00 1 1 x TCSL ••• |
