Microsemi SmartFusion2 - MSS GPIO Reset Functionality

16.2.2 MSS GPIO Reset Functionality
The MSS GPIO outputs can be reset to a predefined state (logic 1 or logic 0) either by the soft resets
coming from the SYSREG block or the power-on reset or the user reset signal (MSS_GPIO_RESET_N)
from the FPGA fabric. The selection of the reset can be done through the MSS Configurator in Libero
SoC or by writing to reset select registers of the SYSREG block. Refer to Table 544, page 578 for reset
select signals.
