Write INSTRUCTION
is missing and the master does not need to know the
slave’s exact INST address.
The command Write INSTRUCTION is designed to en-
able a fast setting of the internal, slave-specific com-
mand registers. The opcode sets the address in the
slave to the lowest command register address. The
instruction data bytes (INST1-INSTn) are send directly
after the OPCODE byte. This command largely cor-
responds to the Write REGISTER (cont.) command,
with the difference that here the addressing sequence

POWER DOWN RESET
The internal power-down reset (low active) is output
through NRES. The enable (rising edge) is delayed
(see R04).
CONFIGURATION NOTES
• Parameter SKO should be programmed to 0x5 so that it is adjusted to suit the signal conditioning chain in iC-LO
(see table 20).
• The light pulse width programmed using parameter PW (see table 10) should be at least 0.5 µs longer than
SKO (see table 20).
• External laser/LED driver latency needs to be considered with the sampling time of iC-LO (parameter SKO see
table 20).
• Operating mode SINGLE_MEASURE only functions when FIN = FIM = 0x0 (see table 18/19).
CHIP REVISION
