Description
Segments control signals
Commons control signals
The pins used for interfacing the SLCD Controller may be multiplexed with PIO lines. Please
refer to product block diagram.
In this case, the assignment of the segment controls and commons are automatically done
depending on COMSEL and SEGSEL in SLCDC_MR. If I/O lines of the SLCD Controller are not
used by the application, they can be used for other purposes by the PIO Controller.
The SLCD Controller is clocked by the slow clock (SCLK). All the timings are based upon a typi-
cal value of 32 kHz for SCLK. The power management of the SLCD controller is handled by the
Shutdown Controller.
The SLCD Controller is supplied by 3V domain.
The SLCD Controller interrupt line is connected to one of the internal sources of the Advanced
Interrupt Controller. Using the SLCD Controller interrupt requires prior programming of the AIC.
The product, embeds 40 segments and 10 Commons.
