Continuous Commands
The device supports the ability to execute commands
continuously. While the CS pin is in the active state (VIL
or VIHH). Any sequence of valid commands may be
received.
The following example is a valid sequence of events:
1.
CS pin driven active (VIL or VIHH).
2.
Read Command.
3.
Increment Command (Wiper 0).
4.
Increment Command (Wiper 0).
5.
Decrement Command (Wiper 1).
6.
Write Command (Volatile memory).
7.
Write Command (Non-Volatile memory).
8.
CS pin driven inactive (VIH).
Note 1: It is recommended that while the CS pin is
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.
2: It
is
also
recommended
that
long
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.
