SERIAL COMMUNICATION FORMAT

The following diagram shows the PT6315 serial communication format. The DOUT Pin is an N-channel, open-drain

output pin, therefore, it is highly recommended that an external pull-up resistor (1KΩ to 10KΩ) must be connected to

DOUT.

where: twait (waiting time)

≥ 1 µs

It must be noted that when the data is read, the waiting time (twait) between the rising of the eighth clock that has set the

command and the falling of the first clock that has read the data is greater or equal to 1 µs.
