8.32 READ PRODUCT IDENTIFICATION (RDID, ABh)
The Release from Power-down/Read Device ID instruction is a multi-purpose instruction. It can support both SPI
and QPI modes. The Read Product Identification (RDID) instruction is for reading out the old style of 8-bit Electronic
Signature, whose values are shown as the table of Product Identification.
The RDID instruction code is followed by three dummy bytes, each bit being latched-in on SI during the rising SCK
edge. 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 RDID instruction is ended by driving CE# high. The Device ID (ID7-ID0) outputs repeatedly if additional
clock cycles are continuously sent to SCK while CE# is at low.
