Function
Equivalent circuit
TIM
20
Timer pin when there is no signal in the zero-cross
circuit.
Forcibly set data when there is no zero-cross signal,
from the time the data is set until the timer ends.
CL
DI
26
25
Input pin for serial data and clock used for control.
CE
24
Chip enable pin. Data is written to the internal latch and
the analog switches are operated when the level
changes from High to Low.
Data transfer is enabled when the level is High.
