7. 16-Bit RAM Address Summary1
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 that the data are twice as long. In addition, one additional
READ cycle is required during READ operations to accommodate the one-deep pipeline architecture. (See "4.16.
SPI Control Interface" on page 50 for more details). All internal RAM addresses are assigned a default value of
zero during initialization and following a system reset. Unless otherwise noted, all RAM addresses use a 2s
complement, MSB first data format (ordered alphabetically by mnemonic).
