To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
1 = Asserts an internal FGPI reset (also output on fgpi_resetn pin)
The effects are:
ALL CLOCKS MUST BE RUNNING before the soft reset can
complete.
This bit will clear after the reset completes.
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
1 = All writes to FGPI MMIO space (except this register) will be
ignored. All reads (except this register) will return 0x00000000.
The FGPI module clock can be stopped low to save power when
this bit is set.

• All FGPI registers are reset
• All pending interrupts are removed
• Any pending DMA writes are aborted (FIFO’s are cleared)
• All state machines return to their reset state
