Notes
1. Crosstalk on output, measured in the unused channel when the other channel is provided with a nominal input signal
(CTI active).
2. A number of more than 31 burst key pulses repeats the counter cycle of delay time control.

Notes
1. S = START condition.
2. SLAVE ADDRESS = 1000 100X.
3. ACK = acknowledge, generated by the slave.
4. SUBADDRESS = subaddress byte, see Table 1.
5. DATA = data byte, see Table 1.
6. P = STOP condition.
7. X = read/write control bit.
X = 0, to write (the circuit is slave receiver only).
If more than 1 byte DATA is transmitted, then auto-increment of the subaddress is performed.
Table 1 I2C-bus transmission; see Table 2
