Regardless of how the CH2TGON bit (CR1-B7) is set, signals input into the CIDATA2 pin
are modulated and output as Caller ID tones. When this bit is set, the level setting by the
CH2TG1LVn (CR16-B7 to B1) bits is valid, but the CH2TG1_n (CR16-B0/CR17-B7 to
B0) bits, CH2RING (CR11-B7) bit, and CH2TG1TRPn (CR11-B6 to B4) bits are invalid.

Regardless of how the CH1TGON bit (CR1-B6) is set, signals input into the CIDATA1 pin
are modulated and output as Caller ID tones. When this bit is set, the level set by the
CH1TG1LVn (CR9-B7 to B1) bits is valid, but the CH1TG1_n (CR9-B0/CR11-B7 to B0)
bits, the CH1RING (CR11-B3) bit, and the CH1TG1TRPn (CR11-B2 to B0) bits are
invalid.
