Ringing Oscillator Inactive Timer.
This register contains the lower 8 bits of the ringing oscillator inactive timer (the silent
time between ringing bursts). Register 27 contains the upper 8 bits of this value. 1.25 µ s/
LSB.
Read returns 10 binary.
Battery Select Indicator.
0 = BATSEL pin is output low. (Si3200 internal battery switch open).
1 = BATSEL pin is output high. (Si3200 internal battery switch closed).
Additional Ringing Rail Present (Third Battery).
0 = Ringing rail not present.
1 = Ringing rail present. For Si3220, RRD/GPO toggles with LINEFEED ringing
cadence.
Relay Driver Output Enable.
0 = Disabled.
1 = Enabled.
General Purpose Output.
0 = GPO output low.
1 = GPO output high.
Read returns zero.
