Remote System Upgrade Status Registers

Table 2-9: Remote System Upgrade Status Register—Current State Logic Bit for MAX 10 Devices

Bits Name Description

33:30 msm_cs The current state of the master state machine (MSM).

29 ru_wd_en

The current state of the enabled user watchdog timer. The default

state is active high.

28:0 wd_timeout_value The current, entire 29-bit watchdog time-out value.

Table 2-10: Remote System Upgrade Status Register—Previous State Bit for MAX 10 Devices

Bits Name Description

31 nconfig An active high field that describes the reconfiguration sources

which caused the MAX 10 device to leave the previous application

configuration. In the event of a tie, the higher bit order takes

precedence. For example, if the nconfig and the ru_nconfig

triggered at the same time, the nconfig takes precedence over the

ru_nconfig.

29 nstatus

28 wdtimer

27:26 Reserved Reserved—set to 0.

25:22 msm_cs

The state of the MSM when a reconfiguration event occurred. The

reconfiguration will cause the device to leave the previous applica‐

tion configuration.

21:0 Reserved Reserved—set to 0.

Master State Machine

The master state machine (MSM) tracks current configuration mode and enables the user watchdog

timer.
