FUNCTIONAL DESCRIPTION
OPERATIONAL MODES
output being controlled ON. Diagnostics is treated in a similar
manner — outputs with a fault will feedback (via SO) to the
MCU a logic [1], while normal operating outputs will provide a
logic [0].
The 33996 may be controlled and provide diagnostics
using a daisy chain configuration or in parallel mode.
Figure 10
shows the daisy chain configuration using the
33996. Data from the MCU is clocked daisy chain through
each device while the Chip Select bit (
CS
) is commanded low
by the MCU. During each clock cycle, output status from the
daisy-chained 33996s is being transferred back to the MCU
via the Master In Slave Out (MISO) line. On rising edge of
CS
,
data stored in the input register is transferred to the output
driver. Daisy chain control of the 33996 requires 24 bits per
device.
Multiple 33996 devices can be controlled in a parallel input
fashion using the SPI.
Figure 11
, page

, illustrates
potentially 32 loads being controlled by two dedicated
parallel MCU ports used for chip select.
