Reference source not found.. 5.2 On-Board Indications ol et e The on-board drivers operate in a 'closed loop'. The evaluation board interfaces with external sensors and thus allows reception of external indications such as: LED string current Power supply's voltage Thermal indication LED color indication These indications allow the internal circuitries to operate in a closed loop mode and stabilize the system in accordance with the preliminary configuration instructions. 5.3 Interfaces bs The evaluation board interfaces with the Host CPU via the UART0, I2C slave and through dedicated control signals. It can also be connected to an external Video controller so as to implement advanced features such as dynamic and scanning BackLight. 5.4 Color Closed Loop The color management function is implemented by the PD23000. The color closed loop is preset by O the user by using the on-board jumpers and switches (see section 3.2 for more details). The loop can operate in any of the following configurations as follow: PD23000 with CMC operation – In these configurations the PD23000 MCU receives color indication from the color sensors connected to J35-J41. The illumination data is then transmitted to the drivers via the MCU when an ESPI communication command is issued. PD23000 without CMC operation – in these configurations there is no need for CMC (for example when white LEDs are utilized). External CMC operation – in this configurations CMC operation is performed by the Host side, The color data is then transmitted to the drivers via the ESPI2 signals.
