AS89010

V3.11

For SYND mode please also address first result register (address 0) and then read 11 bytes. Take care, the

internal counter is only 20 bit. Another way to get the Value of OUTINT is to read this with an address for

each result. Because all output registers are 16 bit, the MSB part of OUTINT is located at address 5. Then

this codes examples will work:

ulOutint=((ULONG)(usaMeasure[5]&0x00ff))<<16;

ulOutint=(ULONG)usaMeasure[4];

6.4 I²C Interface

The two wire serial interface is compatible to the fast mode I²C protocol28 and

timing. The AS89010 can only operate as slave with slave address 11101A1A0,

with the two lower bits defined by the input pins A1, A0. For more details refer to

chapter 5.6. The I²C interface timing diagram is shown in Figure 1, timing

specification in Table 2.

28 In cases of strong interferences (long I²C cables, EMC or others) errors in I²C communication could be possible. In these cases we

suggest to use PCB EMC-protection e.g. an external I²C repeater.
