MAX6964Functional OverviewThe MAX6964 is a general-purpose output (GPO)peripheral that provides 17 output ports, O0–O16, con-trolled through an I2C-co

User RAMThe MAX6964 includes 2 register bytes, which areavailable as general-user RAM (Table 2). These bytesare reset to the value 0xFF on power-up an

MAX6964during the high period of the clock pulse. When themaster is transmitting to the MAX6964, the device gen-erates the acknowledge bit because the

If multiple data bytes are transmitted before a STOP con-dition is detected, these bytes are generally stored insubsequent MAX6964 internal registers
