8.28 SET EXTENDED READ PARAMETERS OPERATION (SERPNV: 85h, SERPV: 83h)

Set Read Operational Driver Strength

This device supports configurable Operational Driver Strength in both SPI and QPI modes by setting three bits

(ODS0, ODS1, ODS2) within the Extended Read Register. To set the ODS bits the SERPNV and SERPV operation

instructions are required.

SERPNV is used to set the non-volatile Extended Read register, while SERPV is used to set the volatile Extended

Read register.

Note:

1. When SERPNV is executed, the volatile Read Extended Register is set as well as the non-volatile Read Extended
