Control words beside No. 1- 10
Not specified Control words are not executed (cause no function) and the shift register (SO
Data) is reset after the
CS
signal (all “0”).
Example for an access to channel 1 to 8:
LLHH LLLL HLLH LLLH: OR operation between parallel inputs and data bits, i.e channel 1, 5
and 8 will be switched on.
The next command is now:
LHHH LLLL HHHH LLLL
LHHH LLLL as command word has no special meaning and will not be accepted. The output
states will not be changed and the shift register will be reset (at the next
CS
SO Data all “0”).
Diagnostics
FAULT
- Fault pin. There is a general fault pin (open drain) which shows a high to low transi-
tion as soon as an error occurs for any one of the sixteen channels. This fault indication can
be used to generate a μC interrupt. Therefore a ‘diagnosis’ interrupt routine need only be
called after this fault indication. This saves processor time compared to a cyclic reading of the
SO information.
As soon as a fault occurs, the fault information is latched into the diagnosis register. A new
error will over-write the old error report. Serial data out pin (SO) is in a high impedance state
when
CS
is high. If
CS
receives a LOW signal, all diagnosis bits can be shifted out serially.
For full diagnosis there are two diagnostic bits per channel configured as shown in Figure 1.
Normal function:
The bit combination
HH
indicates that there is no fault condition, i.e. normal
function.
Overload, Short Circuit to Battery (SCB) or Overtemperature:
HL
is set when the current
limitation gets active, i.e. there is a overload, short to supply or overtemperature condition.
Open load:
An open load condition is detected when the drain voltage decreases below 3 V
(typ.).
LH
bit combination is set.
