21.5.23 GPIO System Reset Control Register

Table 21-29. GPIO_SYSRESET_SEL_CR
Bit Number Name Reset Value Description
[31:4] Reserved 0
3 MSS_GPIO_31_24_SYSRESET_SEL 0 0: Selects the combination of either 
power-on reset or the MSS_GPIO_RESET_N signal from the FPGA fabric to reset the GPIO

1: Causes GPIO[31:24] to be held in reset by the soft reset signal MSS_GPIO_31_24_SOFT_RESET

2 MSS_GPIO_23_16_SYSRESET_SEL 0 0: Selects the combination of either 
power-on reset or the MSS_GPIO_RESET_N signal from the FPGA fabric to reset the GPIO

1: Causes GPIO[23:16] to be held in reset by the soft reset signal MSS_GPIO_23_16_SOFT_RESET

1 MSS_GPIO_15_8_SYSRESET_SEL 0 0: Selects the combination of either power-on reset or the MSS_GPIO_RESET_N signal from the FPGA fabric to reset the GPIO

1: Causes GPIO[15:8] to be held in reset by the soft reset signal MSS_GPIO_15_8_SOFT_RESET

0 MSS_GPIO_7_0_SYSRESET_SEL 0 0: Selects the combination of either power-on reset or the MSS_GPIO_RESET_N signal from the FPGA fabric to reset the GPIO

1: Causes GPIO[7:0] to be held in reset by the soft reset signal MSS_GPIO_7_0_SOFT_RESET

Note: Do not change these register fields dynamically for 005 and 010 devices, see 21.5.1 System Registers Behavior for M2S005/010 Devices.
