1.4.6. Remote Update Operation
The operation defined in the Remote Update Operation column should only be performed in the corresponding master state machine (MSM) mode.

read_source
The following table lists the details for read_source. read_source specifies whether a parameter value is read from the current or a previous state. When you trigger the read operation, all contents in the status register or input register latched to the data_out node in the Remote Update Intel® FPGA IP core.
read_source | Description |
---|---|
00 | Current state contents in status register |
01 | Previous state register 1 contents in status register |
10 | Previous state register 2 contents in status register |
11 | Current contents is in input register |
The previous state register 1 reflects the current application configuration and the previous state register 2 reflects the previous application configuration.
