Note 1: It is recommended that while the CS pin is
2: It is also recommended that long
active, only one type of command should
be issued. When changing commands, it
is recommended to take the CS pin
inactive then force it back to the active
state.
command strings should be broken down
into shorter command strings. This
reduces the probability of noise on the
SCK pin corrupting the desired SPI
command string.
