PRODUCTION DATA.
Status information data (SID) is 132 bits long and contains device status information and LED fault information. Table 22 describes the bit mapping when SID data loads into the common shift register.
Bits 287–240 are the LED-open information for the output channels, bits 203–144 are the LED-short information for the output channels, bits 239-216 are the adjacent-pin-short information for the output channels, bits 215–206 are the error status registers, bits 205–204 are the negate bits, and other bits are reserved registers.
After power on, all error status registers are set to 0. If any one of the error-status-register flags (bits 215–206) asserts, the registers latch the faults until a reset error command is executed to clear the faults. But the LOD_LSD data continues to update every PWM cycle.
