Registers of the PCF8553...continued [1] See Table 9. For writing to the registers, send the address byte first, then write the data to the register (see Section 10.1.4 and Section 10.2.1). The address byte works as an address pointer. For the succeeding registers, the address pointer is automatically incremented by 1 (see Figure 3) and all following data are written into these register addresses. After register 17h, the auto-incrementing will stop and data are ignored. aaa-011661 address counter 00h auto-increment 01h 02h 03h ... 15h 16h 17h Figure 3.
