Read Data Bytes (READ)
The Read Data Bytes (READ) command reads data from the memory array at the frequency (f
the SCK input, with a maximum speed of 40 MHz. The host system must first select the device by driving CS#
low. The READ command is then written to SI, followed by a 3 byte address (A23-A0). Each bit is latched on
the rising edge of SCK. The memory array data, at that address, are output serially on SO at a frequency f
on the falling edge of SCK.
Figure 9.1
can start at any location of the memory array. The device automatically increments to the next higher address
after each byte of data is output. The entire memory array can therefore be read with a single READ
command. When the highest address is reached, the address counter reverts to 00000h, allowing the read
sequence to continue indefinitely.
The READ command is terminated by driving CS# high at any time during data output. The device rejects any
READ command issued while it is executing a program, erase, or Write Registers operation, and continues
the operation uninterrupted.
