When set, the DAA responds automatically to a collapse of the line-derived power supply dur-
ing a billing tone event. When off-hook, if BTE = 1 and BTD goes high, the dc termination is
released (800 Ω presented to line). If BTE and RIM (U70, bit 9) are set, an RI (U70, bit 1)
interrupt also occurs when BTD goes high.
Receive Overload.
The bit is set when the receive input (i.e., receive pin goes below ground) has an excessive
input level. This bit is cleared by writing a 0 to this location.
0 = Normal receive input level.
1
Billing Tone Detected.
This bit is set if a billing tone is detected. This bit is cleared by writing a 0 to this location.
