Register Access Commands
Read Serial Flash Discoverable Parameters (RSFDP 5Ah)
Read Status Register-1 (RDSR1 05h):
The command is initiated by shifting on SI the instruction code “5Ah”, followed by a 24-bit address of
000000h, followed by eight dummy cycles. The SFDP bytes are then shifted out on SO starting at the falling
edge of SCK after the eight dummy cycles. The SFDP bytes are always shifted out with the MSB first. If the
24-bit address is set to any other value, the selected location in the SFDP space is the starting point of the
data read. This enables random access to any parameter in the SFDP space. The maximum clock frequency
for the RSFDP command is 133 MHz.
The Read Status Register-1 (RDSR1) command allows the Status Register-1 contents to be read from SO.
The Status Register-1 contents may be read at any time, even while a program, erase, or write operation is in
progress. It is possible to read the Status Register-1 continuously by providing multiples of eight clock cycles.
The status is updated for each eight cycle read. The maximum clock frequency for the RDSR1 (05h)
command is 133 MHz.
