DEVICE OPERATION (CONTINUED)
RDID COMMAND (READ PRODUCT IDENTIFICATION)
OPERATION
The Read Product Identification (RDID) instruction is for
reading out the old style of 8-bit Electronic Signature, whose
values are shown as table of ID Definitions. This is not same
as RDID or JEDEC ID instruction. It’s not recommended to
use for new design. For new design, please use RDID or
JEDEC ID instruction.
The RDES instruction code is followed by three dummy
bytes, each bit being latched-in on SI during the rising
edge of SCK. Then the Device ID is shifted out on SO
with the MSB first, each bit been shifted out during the
falling edge of SCK. The RDES instruction is ended by
CE# goes high. The Device ID outputs repeatedly if
continuously send the additional clock cycles on SCK while
CE# is at low.
