DATASHEET

Automatic reads and writes happen when there is an external XDATA read or write, using the serial

stream that has been previously discussed.

7.1.5

Erase Example

To perform a SCTR_ERASE, 32BLK_ERASE, or 64BLK_ERASE, the device writes 0x20, 0x52, or

0xD8, respectively to the first byte of the command buffer, followed by a 3-byte address. The length

of the transfer is set to 4 bytes. To perform this, the device drives SPI_CE_N low, then counts out 8

clocks. It then outputs on SPI_DO the 8 bits of command, followed by 24 bits of address of the location

to be erased. When the transfer is complete, SPI_CE_N goes high, while the SPI_DI line is ignored

in this example.
