5.13 Read with 4-Byte Address

The READ instruction (13H) is supported only in SPI mode and operates at clock frequencies up to 108 MHz. This instruction is not supported in QPI mode. During execution, the device outputs data on SIO[1], starting from the specified address location, and continuously streams data through successive addresses until the operation is terminated by a low-to-high transition on CE#. The internal Address Pointer automatically increments after each byte read. Once the highest memory address is reached, the Address Pointer wraps around to address location 00000000H.

To initiate the read instruction, the host issues the 8-bit command (13H), followed by a 4-byte address. CE# must remain active-low for the duration of the read cycle. Refer to Figure 5-7 for the command sequence.
