DPDPOR

Deep Power Down

power saving mode

entry selection upon

POR

N -> R/W

V -> R

Description: The DPDPOR bit selects if the device will be in

either Deep Power Down (DPD) mode or the Standby mode

after the completion of POR. If enabled, DPDPOR configures

the device to start in DPD mode to reduce current

consumption until the device is needed. If the device is in

DPD, a pulse on CS# or a Hardware reset will return the device

to Standby mode.

Selection Options:

0 = Standby mode is entered upon the completion of POR

1 = Deep Power Down Power mode is entered upon the

completion of POR

Read Burst Wrap Length

selection

N -> R/W

V -> R/W

Description: The RBSTWL[1:0] bits select the read burst wrap

length and alignment during normal operation. It selects the

fixed length/aligned group of 8-, 16-, 32-, or 64-bytes.

Selection Options:

00 = 8 Bytes Wrap length

01 = 16 Bytes Wrap length

10 = 32 Bytes Wrap length

11 = 64 Bytes Wrap length

Dependency: RBSTWP (CFR4x[4])
