b0=LSB of decoded DTMF digit and shifted out first.
Powerdown Mode (MT317xB/337xB)
The MT317xB/337xB devices offer a powerdown function to preserve power consumption when the device is not in
use. A logic high can be applied at the PWDN pin to place the device in powerdown mode. The ACK pin should be
kept at logic low to avoid undefined ESt/DStD and SD outputs (see Table 2).
