8.27 SET READ REGISTER OPERATION (SRRNV: 65h, SRRV: C0h/63h)

Set Read Register Bits

This device supports configurable burst length and dummy cycles in both SPI and QPI mode by setting three bits

(P2, P1, P0) and four bits (P6, P5, P4, P3) within the Read Register, respectively. To set those bits the SRRNV

and SRRV operation instruction are used. Details regarding burst length and dummy cycles can be found in Table

6.9, Table 6.10, and Table 6.11. HOLD#/RESET# function selection (P7) bit in the Read Register can be set with

the SRRNV and SRRV operation as well, in order to select HOLD#/RESET# pin as RESET# or HOLD#.

For the device with dedicated RESET# pin (or ball), RESET# pin (or ball) will be a separate pin (or ball) and it is

independent of the P7 bit setting in Read Register.

SRRNV is used to set the non-volatile Read Register, while SRRV is used to set the volatile Read Register.

To write non-volatile Read Register bits, a standard Write Enable (06h) instruction must previously have been

executed for the device to accept SRRNV (65h) instruction (Status Register bit WEL must equal “1”).

To write volatile Read Register bits (SRRV), 63h or C0h command can be used.

When using 63h instruction, a standard Write Enable (06h) instruction must previously have been executed for the

device to accept SRRV (63h) instruction (Status Register bit WEL must equal “1”).

But C0h instruction does not require a standard Write Enable (06h) operation. (Status Register bit WEL remains

“0”).

Note: When SRRNV is executed, the volatile Read Register is set as well as the non-volatile Read Register.
