Read Flag Status Register
The Read Flag Status Register (RFSR) instruction allows the Flag Status Register to be
read.
Apart form the parallelizing of the instruction code and the output data on the two pins DQ0
and DQ1, the instruction functionality is exactly the same as the Read Flag Status Register
(RFSR) instruction of the Extended SPI protocol, please refer to Section 9.1.26: Read Flag
Status Register for further details.
