Activates DTMF. The selected DTMF tones are
transmitted continuously when this bit is high and TX
ENABLE (CR0, Bit 1) is set to one. TX DTMF
overrides all other transmit functions.
D5 interacts with bits D4 and D0 as shown.
Disables answer tone generator.
Enables answer tone generator. A 2225 Hz answer
tone will be transmitted continuously when the
TRANSMIT ENABLE bit is set in CR0. The device
must be in answer mode.
