auto mode operation. The output data is read out using the same timing as that used when CE = OE = V
Read Mode. The
Hardware Sequence flag is read to determine the device status and the result of the operation is verified by
comparing the read-out data with the original data.
The TC58FVT321/B321 has a Hardware Sequence flag which allows the device status to be determined during an

function. DATA polling begins on the rising edge of WE in the last bus cycle. In an Auto-Program operation,
DQ7 outputs inverted data during the programming operation and outputs actual data after programming has
finished. In an auto-erase operation, DQ7 outputs 0 during the Erase operation and outputs 1 when the Erase
operation has finished. If an Auto-Program or auto-erase operation fails, DQ7 simply outputs the data.

During an Auto-Program or auto-erase operation, the device status can be determined using the data polling
When the operation has finished, the address latch is reset. Data polling is asynchronous with the OE signal.
DQ0 and DQ1 pins are reserved for future use.
0 is output on DQ0, DQ1 and DQ4.
