2.7
CS, normally High, is set Low during the transmission / reception of a byte, lasting 8CCLK
pulses.
Though, in general, two bytes of the same instruction take two CS separated cycles,
STLC5046 can handle the data transfer in a single 16 CCLK CS cycle, in both the directions.
One additional wire provided to the control interface is an open drain interrupt output (INT)
that goes low when a change of status is detected on the I/O pins.
SLIC control interface
The device provides 12 I/O pins plus 4 CS signals. The interface can work in dynamic or
static mode: it can be selected by means of DIR register.

●
Dynamic Mode: the I/O pins are configured as input or output by means of DIR register.
The CS signals are used to select the different SLIC interface. In this case the I/O pin
can be multiplexed. The data loaded from SLIC#n via I/O pins configured as input can
be read in the DATAn register. The data written in a DATAn register will be loaded on the
I/O pins configured as output when the Csn signal will be active.
Static Mode: The CS signal can be used as I/O pins. They can be configured as input
or output I/O by means of DATA1 register. The data corresponding to the CS signal can
be read or written by means of DATA2 register. All data related to th other I/O pins can
be read or written by means of DATA0 register.
