(1) R = read, W = write
(2) Default value
(3) At power up, in order to initialize the Error Flags registers, the host must write 1 to bit 7 of the MODE2 register and then write 0 to bit 7
of the MODE2 register.
Open-Circuit Detection
The TLC59116 LED open-circuit detection compares the effective current level I_OUT with the open load detection
threshold current I_OUT,Th. If I_OUT is below the threshold I_OUT,Th the TLC59116 detects an open load condition. This
error status can be read out as an error flag through the registers EFLAG1 and EFLAG2.
