9-6. Read Data Bytes (READ)
The read instruction is for reading data out. The address is latched on rising edge of SCLK, and data shifts out
on the falling edge of SCLK at a maximum frequency fR. The first address byte can be at any location. The ad-
dress is automatically increased to the next higher address after each byte data is shifted out, so the whole
memory can be read out at a single READ instruction. The address counter rolls over to 0 when the highest ad-
dress has been reached.
The sequence of issuing READ instruction is: CS# goes low→ sending READ instruction code→3-byte address
on SI →data out on SO→ to end READ operation can use CS# to high at any time during data out.
