Read Suspend Status Register (RDSSR) (09h)
The Read Suspend Status Register (RDSSR) instruction allows the Suspend Status Register to be
read. The Suspend Status Register may be read at any time, even while a Write Suspend or Write
Resume cycle is in progress. When one of these cycles is in progress, it is recommended to check the
Write In Progress (WIP) bit before sending a new instruction to the device. It is also possible to read the
Suspend Status Register continuously, as shown in Figure 10.
The instruction sequence is shown in Figure 10.1 while using the Enable Quad I/O (EQIO) (38h) command.
