Data Sheet
TOP (Transfer Operation) Command
The TOP (transfer operation) command, a GCI command, is used when no status modification of the Le58083 Octal SLAC device
is required. The byte transmission sequence for a TOP command is shown in Table Table 10.

The revision code of the Le58083 Octal SLAC device will be 14h or higher.
SOP (Status Operation) Command
To modify or evaluate the Le58083 Octal SLAC device status, the contents of configuration registers CR1–CR5 and the SLIC
device I/O register can be transferred to and from the Le58083 Octal SLAC device. This is done by a SOP (Status Operation)
command, which is a GCI command. The general transmission sequence of the SOP command is shown in Table Table 11.
