Power-on/Reset State
When power is first applied to the device, or when recovering from a reset condition, the device
will default to SPI Mode 3. In addition, the SO pin will be in a high-impedance state, and a high-
to-low transition on the CS pin will be required to start a valid instruction. The SPI mode will be
automatically selected on every falling edge of CS by sampling the inactive clock state. After
power is applied and V
CC
is at the minimum datasheet value, the system should wait 20 ms
before an operational mode is started.

r = Reserved Bit
P = Page Address Bit
