The host sets S5T8610 into DTMF mode by sending this command with the LSB set to 1. S5T8610 still operates
the modem in DTMF mode so that the DTMF tones can be monitored. The host sets the S5T8610 back to normal
operation, in which the ADPCM and modem are running, by using this command with the LSB set to 0.

The DTMF tone is generated for 100msec after receiving this command. The tone is generated through the
DTMF pin. The RXO pin is set mute during the DTMF generation mode. This command only operates when
S5T8610 is set to DTMF mode. When DTMF mode is not set, this command is ignored. Since S5T8610 must
receive this command to generate a DTMF tone, there is no default value.
