9 / 25 page MITSUBISHI LSIs 16,777,216-BIT (2097,152-WORD BY 8-BIT / 1048,576-WORD BY16-BIT) CMOS 3.3V-ONLY, BLOCK ERASE FLASH MEMORY M5M29GB/T160BVP-80 Sep 1999. Rev2.0 9 *The RY/BY# is an open drain output pin and indicates status of the internal WSM. When low,it indicates that the WSM is Busy performing an operation. A pull-up resistor of 10K-100K Ohms is required to allow the RY/BY# signal to transition high indicating a Ready WSM condition. STATUS REGISTER Status Erase Status Program Status Definition Symbol (DQ5) (DQ4) Write State Machine Status (DQ7) (DQ6) (DQ1) (DQ0) (DQ3) (DQ2) "1" "0" Ready Busy Suspended Operation in Progress / Completed Error Successful Error Successful SR.5 SR.4 SR.7 SR.6 SR.1 SR.0 SR.3 SR.2 Block Status after Program Reserved - Suspend Status Error Successful - *DQ3 indicates the block status after the page programming, byte/word programming and page buffer to flash. When DQ3 is "1", the page has the over-programed cell . If over-program occurs, the device is block fail. However if DQ3 is "1", please try the block erase to the block. The block may revive.

WP# pins must not be switched during performing Erase / Write operations or WSM Busy (WSMS = 0). 2) Erase/Write command for locked blocks is aborted. At this time read mode is not array read mode but status read mode and 00B0H is read. Please issue Clear Status Register command plus Read Array command to change the mode from status read mode to array read mode. |
