All commands that require additional input data to the device must have the input data as the next N words written into the device
(for example, framed by the next N transitions of CS). All unused bits must be programmed as 0 to ensure compatibility with future
parts. All commands that are followed by output data will cause the device to output data for the next N transitions of CS going
Low. The QLSLAC device will not accept any commands until all the data has been shifted out. The output values of unused bits
are not specified.
An MPI cycle is defined by transitions of CS and DCLK. If the CS lines are held in the High state between accesses, the DCLK
may run continuously with no change to the internal control data. Using this method, the same DCLK can be run to a number of
QLSLAC devices, and the individual CS lines will select the appropriate device to access. Between command sequences, DCLK
can stay in the High state indefinitely with no loss of internal control information regardless of any transitions on the CS lines.
Between bytes of a multibyte read or write command sequence, DCLK can also stay in the High state indefinitely. DCLK can stay
in the Low state indefinitely with no loss of internal control information, provided the CS lines remain at a High level.
If a low period of CS contains less than 8 positive DCLK transitions, it is ignored. If it contains 8 to 15 positive transitions, only
the last 8 transitions matter. If it contains 16 or more positive transitions, a hardware reset in the part occurs. If the chip is in the
middle of a read sequence when CS goes Low, data will be present at the DIO pin even if DCLK has no activity. If CS is held low
for two or more cycles of Frame Sync (FS) and DCLK is static (no toggling), then the QLSLAC device switches to the General
Circuit Interface mode of operation.
