Write INSTRUCTION

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

is missing and the master does not need to know the

slave’s exact INST address.

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

The parameter REV in the iC-LO ROM provides the

chip revision.
