Table 10.27 DYB Access Register (DYBAR)
Bits
7 to 0
Field Name Function
DYB
Read or Write
per sector DYB
Type
Volatile
Default State
Description
00h = DYB for the sector addressed by the DYBRD or DYBP
command is cleared to ‘0’, protecting that sector from program or
FFh
erase operations.
FFh = DYB for the sector addressed by the DYBRD or DYBP
command is set to ‘1’, not protecting that sector from program or
erase operations.
Table 10.28 Non-Volatile Data Learning Register (NVDLR)
Bits Field Name Function
7 to 0
NVDLP
Non-Volatile
Data Learning
Pattern
Type
OTP
Default State
Description
OTP value that may be transferred to the host during DDR read
00h
command latency (dummy) cycles to provide a training pattern to
help the host more accurately center the data capture point in the
received data bits.
Table 10.29 Volatile Data Learning Register (NVDLR)
Bits Field Name Function
7 to 0
VDLP
Volatile Data
Learning
Pattern
Type
Volatile
Default State
Description
Takes the
value of
NVDLR
during POR
or Reset
Volatile copy of the NVDLP used to enable and deliver the Data
Learning Pattern (DLP) to the outputs. The VDLP may be changed
by the host during system operation.
10.4 Initial Delivery State
The device is shipped from Cypress with non-volatile bits set as follows:
The entire memory array is erased: i.e. all bits are set to 1 (each byte contains FFh).
The OTP address space has the first 16 bytes programmed to a random number. All other bytes are erased to FFh.
The ID-CFI address space contains the values as defined in the description of the ID-CFI address space.
The Status Register 1 contains 00h (all SR1 bits are cleared to 0’s).
The Configuration Register 1 contains 00h.
The Autoboot register contains 00h.
The Password Register contains FFFFFFFF-FFFFFFFFh.
All PPB bits are 1.
The ASP Register contents depend on the ordering options selected:
