4 led control ic W2RF004RM operation functional overview receiving commands the ic recieves commands with two-wire serial communication to control 9 led lines. commands ar e received in a 40-bits-per-com mand com- munication format. gradation control the lighting of the 9 led lines is cont rolled individually or by group with 16-le vel lighting gradation and 32-level lighting s peed. the exponential control of output duty cycle allows lighting gradation that matches the human visual characterist ics. in addition, the specific ation of lighting speed allows fade-in and fade-out with up to 1,024 levels. number of control lines the ic has two device address lines, each of which can be configured in seven ways by te rminal configuration. this provides up to 49 patterns of device address configuration, al lowing up to 441 lines to be controlled on the same communication line. two device address line s can be combined to configure a device group. communication specifications input signals to sda-i and scl-i are input via the filt er circuit (0.1 s delay) to the communication circuit. an sda-i signal that is input to the com- munication circuit is taken in as serial data at the rising e dge of an scl-i signal. when serial data is received in a differen t format from the com- munication format, the data will be invalid. when the start signal, ?111111111? is detected, the communication ci rcuit takes in data as new serial data, whether it is on st and-by or in the middle of intake of serial data. input signals to sda-i and scl-i will be output via the asynchronous buffer to sda- o and scl-o without going through the filter circuit. description of communication format control command device selection data (8 bits) the device id is fixed. the correspondence between the device addresses a and b and the setting terminals adra0 to 2 and adrb0 to 2 is shown in the table.
