NOTES:
10. The logic presented to the signal pin TXT1, TXT2 changes the decoder threshold during tone Transmit and Receive. TTH1, TTH2 allows
threshold control through the I2C provided that TXT1, TXT2 = 0
11. The tone rise and fall times are not shown due to resolution of graphics. It is 10µs typ for 22kHz.
12. The EXTM1, EXTM2 pins have input thresholds of VIL(max) = 0.8V and VIH(min) = 1.7V
