White Board
8.5 H-bridge driver
There is an H-Bridge driver on this board which is controlled by MCU SPI interface. It can
be used for brushed DC motor control.

8.6 Switch inputs detection
The MSDI device CD1030 includes 21 switch-to-ground inputs and 12 programmable
inputs (switch to battery or ground). There are 6 channels SG (Switch-to-Ground inputs)
pins and 6 channels SP (Switch to Programmable input) pins which are implemented on
the White Board. The switch status, either open or closed, can be read by MCU through
an SPI interface. Two push buttons – SW8 and SW9 – are used to trigger the switch
status transition for test purpose.

8.7 User peripherals
The user buttons, user LEDs, ADC POTs and touch sense pads on the White Board are
shown in below figure. The related MCU PINs information are listed in Table 6.
