16-Bit RAM Address Summary
All internal 16-bit RAM addresses can be assigned unique values for each SLIC channel and are accessed in a
similar manner as the 8-bit control registers except the data is twice as long. In addition, one more READ cycle is
required during READ operations to accommodate the one-deep pipeline architecture. See "SPI Control Interface"
on page 62 for more details. All internal RAM addresses are assigned a default value of 0 during initialization and
following a system reset. Unless otherwise noted, all RAM addresses use a 2’s complement, MSB first date format.
Refer to AN58 “Dual ProSLIC Programmer Guide” for detailed RAM location descriptions and recommended
settings.
Note: Any RAM address not listed is reserved and must not be written. (ordered alphabetically by mnemonic)

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.
