... Stop or a repeated Start condition during this time period. I/O OPERATIONS (see also Figure 7) Each of the PTN3501’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). ...

... Philips Semiconductors Maintenance and control device Interrupt (see Figs 11 and 12) The PTN3501 provides an open drain output (INT) which can be fed to a corresponding input of the microcontroller. This gives these chips a type of master function which can initiate an action elsewhere in the system. An interrupt is generated by any rising or falling edge of the port inputs in the input mode ...

... 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 14) To perform a byte write the start condition is followed by the memory slave address and the R/W bit set to 0. The PTN3501 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 17) The PTN3501’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. ...
