Note:
1. For extended SPI protocol, C_x = 7 + (A[MAX] + 1).
For dual SPI protocol, C_x = 3 + ((A[MAX] + 1)/2).
For quad SPI protocol, C_x = 1 + ((A[MAX] + 1)/4).
CLEAR FLAG STATUS REGISTER Command
To execute the CLEAR FLAG STATUS REGISTER command and reset the error bits
(erase, program, and protection), S# is driven LOW. For extended SPI protocol, the com-
mand code is input on DQ0. For dual SPI protocol, the command code is input on
DQ[1:0]. For quad SPI protocol, the command code is input on DQ[3:0]. The operation
is terminated by driving S# HIGH at any time.
