Asynchronous Start
Following any Start condition on the bus, a minimum of 9 SCL clock cycles must be completed before a Stop condition can be issued. The
device does not support a Stop or a repeated Start condition during this time period.
I/O OPERATIONS (see also Figure 7)
Each of the PTN3500’s eight I/Os can be independently used as an input or output. Input I/O data is transferred from the port to the
microcontroller by the READ mode (See Figure 10). Output data is transmitted to the port by the I/O WRITE mode (see Figure 9).
