... The eight quasi bidirectional data pins can be independently assigned as inputs or outputs to monitor board level status or activate indicator devices such as LEDs. The PTN3500 has three address pins allowing devices to 2 share the common two wire I C software protocol serial data bus. ...

... 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). ...

... A quasi-bidirectional I/O can be used as an input or output without the use of a control signal for data direction. At power-on the I/Os are HIGH. In this mode, only a current source active. An additional strong pull- These devices turn on when an output is written HIGH, and are switched off by the negative edge of SCL. The I/Os should be HIGH before being used as inputs.

... Byte Write (see Figure 12) To perform a byte write the start condition is followed by the memory slave address and the R/W bit set to 0. The PTN3500 will respond with an acknowledge and then consider the next eight bits sent as the word address and the eight bits after the word address as the data ...

... There is no ninth clock cycle for the acknowledge. Random Read (see Figure 15) The PTN3500’s random read mode allows the address to be read from to be specified by the master. This is done by performing a dummy write to set the address counter to the location to be read. ...
