1 0 = connect to ground, 1 = connect to DVDD. In the case of a pull-down state, connect to ground via a 47 kΩ resistor. In the case of a pull-up state, connect to DVDD

via a 47 kΩ resistor.

I2C Read and Write Operations

Figure 72 shows the timing of a single-word write operation.

Every ninth clock, the SSM3582 issues an acknowledge by

pulling SDA low.

Figure 73 shows the timing of a burst mode write sequence.

This figure shows an example where the target destination

registers are two bytes. The SSM3582 knows to increment its

subaddress register every byte because the requested subaddress

corresponds to a register or memory area with a byte word

length.

The timing of a single-word read operation is shown in

Figure 74. Note that the first R/W bit is 0, indicating a write

operation, because the subaddress must still be written to set up

the internal address. After the SSM3582 acknowledges the

receipt of the subaddress, the master must issue a repeated start

command, followed by the chip address byte with the R/W set

to 1 (read). This repeated command causes the SSM3582 SDA

to reverse and to begin driving data back to the master. The master

then responds every ninth pulse with an acknowledge pulse to

the SSM3582. Refer to Table 17 for a list of abbreviations in

Figure 72 through Figure 75.
