If the bits of HS- and LS-driver of the same output stage are high, the internal logic prevents that both drivers of this output stage can
be switched on simultaneously in order to avoid a high internal current from V
S
to GND.
A logical NOR-combination of all bits 1 to 14 in both status registers. This bit can be polled by the micro-controller without the need
of the full SPI communication (see Figure 13). A broken VCC-connection of the L9949 can be detected by the microcontroller, because
all 15 bits low or high is not a valid frame.
