7 / 33 page TC62D776CFG 2011-12-07 7 About the operation of each command S0 command (Input of output ON/OFF data.) Description If SCK pulses High zero or one time while TRANS is High, it is interpreted as the S0 command, which acts as follows. Basic input pattern of S0 command Input form of output ON/OFF data MSB LSB D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 15 OUT 14 OUT 13 OUT 12 OUT 11 OUT 10 OUT 9 OUT 8 OUT OUT7 OUT6 OUT5 OUT4 OUT3 2 OUT OUT1 OUT0 Input in MSB first. Output ON/OFF data setting Input Data Setting 1 Output turn on 0 Output turn off Default after power-on Data Setting 0 Output turn off Automatic Error Detection Mode If output open/short detection is enabled, its result is automatically transferred from the Error Detection Result register to the 16-bit Shift Register, which can be shifted out from the SOUT pin. Output open/short detection can be enabled with the S3 command. Open/short errors can be detected only for output channels that are enabled for at least 800 ns (Note 1) and are configured to be turned on. For the disabled output channels, the detection result will be 1 (normal). If the output channels stay on for no longer than 800 ns, the automatic error detection result will be invalid; in this case, the detection results of all channels will be 1 (normal). Note 1: Automatic error detection is triggered by the falling edge of the ENABLE signal. Thus, this feature can not be used when ENABLE is tied Low. In the figure shown below, the outputs are enabled for over 800 ns during the Terr2 period, but the automatic error detection result is invalid; thus, it should be kept in mind that the detection results will be 1 (normal) for all channels. |
