SDA9410
’1’, then the store command was sent, but the data aren’t made available yet. If these
bits are ’0’ then the data were made valid and a new write or read cycle can start. The
bits VIMSTATUS, VISSTATUS and OSSTATUS may be checked before writing or
reading new data, otherwise data can be lost by overwriting.
Furthermore the bits NMSTATUS (status of noise measurement: NOISEME) and
LBDSTATUS (status of letter box I²C Bus parameters: SLAA, ELAA, STATUS_SLAA,
STATUS_ELAA, RELY) exist. NMSTATUS signalizes a new value for NOISEME. So if
NMSTATUS is read as ’0’ the current noise measurement has not been updated. If the
NMSTATUS is read as ’1’ a new noise measurement value can be read. LBSTATUS
signalizes at least a change of one of the I²C Bus parameters: SLAA, ELAA,
STATUS_SLAA, STATUS_ELAA, RELY. If the LBDSTATUS is read as ’0’ none of the
I²C Bus parameters has changed its value. If the LBDSTATUS is read as ’1’ at least one
of the I²C Bus parameters has changed its value.
The transmitted data are internally stored in registers. Writing or reading from a not
existing register is permitted and does not generate a fault by the IC.
After switching on the IC (after reset), all bits of the SDA 9410 are set to defined states.
