Any register not listed is reserved and must not be written.
Only positive input values are valid for these RAM addresses.
Si3225 only.
Si3220 only.
For the Si3220, the RINGFRHI RAM address location is used to store the high byte of the internal ringing signal frequency. For the Si3225, this address location stores the desired time delay
between when the relay opens and when the LFS register transitions out of the ringing state.
For the Si3220, the RINGAMP RAM address location is used to store the amplitude of the internal ringing signal. For the Si3225, this address location stores the desired time relay between the last
zero current crossing and the next opportunity to open the ringing relay.
RAM address in decimal.
