... When doing Sector Unprotect, all the other sectors should be protected first. The second method is meant for programming equipment. This method requires V both OE# and A9 pin and non-standard microprocessor timings are used. This method is described in a separate document called EN29LV400A Supplement, representative of Eon Silicon Devices, Inc.

... COMMAND DEFINITIONS The operations of the EN29LV400A are selected by one or more commands written into the command register to perform Read/Reset Memory, Read ID, Read Sector Protection, Program, Sector Erase, Chip Erase, Erase Suspend and Erase Resume. Commands are made up of data sequences written at specific addresses via the command register. ...
Page 12
... Word / Byte Programming Command The device may be programmed by byte or by word, depending on the state of the Byte# Pin. Programming the EN29LV400A is performed by using a four bus-cycle operation (two unlock write cycles followed by the Program Setup command and Program Data Write cycle). When the program command is executed, no additional CPU controls or timings are necessary ...

... Another Erase Suspend command can be written after the device has resumed erasing. WRITE OPERATION STATUS DQ7: DATA# Polling The EN29LV400A provides DATA# polling on DQ7 to indicate the status of the embedded operations. The DATA# polling feature is active during the embedded Programming, Sector Erase, Chip Erase, and Erase Suspend. (See Table 6) When the embedded Programming is in progress, an attempt to read the device will produce the complement of the data written to DQ7 ...

... Erase Suspend mode the standby mode. DQ6: Toggle Bit I The EN29LV400A provides a “Toggle Bit” on DQ6 to indicate the status of the embedded programming and erase operations. (See Table 6) During an embedded Program or Erase operation, successive attempts to read data from the device at any address (by active OE# and CE#) will result in DQ6 toggling between “ ...
