The READ instruction (03H) is supported in SPI mode only,
with a maximum clock frequency of 108 MHz. This command is not supported in QPI mode. Upon
execution, the device outputs data on SO/SIO[1], starting from the specified address, 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. When the highest memory address is reached, the Address Pointer
returns to address location 000000H.
To initiate a READ operation, the host issues the 8-bit
read command (03H), followed by three bytes. CE# must remain active-low for the duration of
the read cycle (see Figure 5-5 for the
read sequence).Figure 5-5. Read Sequence (SPI)
