Release from Deep Power-Down

and Read ID

Release from Deep Power-Down (RDPD) and Read ID

instruction exits Deep Power-Down mode. To exit Deep

Power-Down mode, execute the RDPD. During this

command, the host drives CE# low, then sends the

Deep Power-Down command cycle (ABH), and then

drives CE# high. The device will return to Standby

mode and be ready for the next instruction after TSBR.

To execute RDPD and read the Device ID, the host

drives CE# low then sends the Deep Power-Down

command cycle (ABH), three dummy clock cycles, and

then drives CE# high. The device outputs the Device ID

on the falling edge of the SCK signal following the

dummy cycles. The data output stream is continuous

until terminated by a low-to-high transition on CE, and

will return to Standby mode and be ready for the next

instruction after TSBR. See Figures 5-42 and 5-43 for

the command sequence.
