3.5.10
If DELM = 1, delay transmission is enabled. A delayed
transmission is indicated by inverting the lower nibble
of the discrimination value. The Delay mode is primarily
for compatibility with previous K
not recommended for new designs.

If TIMO = 1, the time-out is enabled. Time-out can be
used to terminate accidental continuous transmissions.
When time-out occurs, the PWM output is set low and

the LED is turned off. Current consumption will be
higher than in Standby mode since current will flow
through the activated input resistors. This state can be
exited only after all inputs are taken low. TIMO = 0, will
enable continuous transmission (Table 3-7).
