    Tone Generator Control Register (TGC: $01A):
    Three-bit write-only register, which controls the
    start/stop of the DTMF signal output as shown in figure 90, and is reset to $0 by MCU reset. TONER and
    TONEC output can be independently controlled by bits 3 and 2 (TGC3, TGC2), and the DTMF circuit is
    controlled by bit 1 (TGC1) of this register.
