9 / 33 page TC62D776CFG 2011-12-07 9 S1 command (Output open/short detection function manual operation is executed.) Description If SCK pulses High five or six times while TRANS is High, it is interpreted as the S1 command, which acts as follows. If output open/short detection is enabled, a current of approximately 60 μA is forced to flow to all the outputs during the tON(S1) period in order to perform open/short detection. tON(S1) is approximately 800 ns long. Its result is immediately transferred to the 16-bit Shift Register, which can be shifted out from the SOUT pin. The format used to transfer the detection result is the same as for the S0 command. Output open/short detection can be enabled with the S3 command. Note: The S1 command should be loaded when the outputs are off. The S1 command is not executed if it is loaded when ENABLE = Low.The S1 command is not also executed when output open/short detection is disabled. SCK should not be applied during the tON(S1) period. Basic input pattern of S1 command After the S1 command is loaded, the first SCK pulse (marked X above) is used to transfer an error detection result to the 16-bit Shift Register. At this time, the TC62D776CFG ignores the SIN input. |
