Offset R/W Width
(Bits)
Description
2 W 32
• Bit 0—trigger read operation from the user watchdog.
• Bit 1—trigger read operation from the previous state applica‐
tion 2 register.
• Bit 2—trigger read operation from the previous state applica‐
tion 1 register.
• Bit 3—trigger read operation from the input register.
• Bit 31:4—reserved.
The
busy
signal is generated right after the write cycle.
3 R 32
• Bit 0—IP
busy
signal.
• Bit 31:1—reserved.
The
busy
signal indicates the Dual Configuration IP core is in the
writing or reading process. In this state, all write operation to the
remote system upgrade block registers operation request are
ignored except for triggering the reset timer. Altera recommends
you to pull this
busy
signal once you triggered any read or write
process.
4 R 32
• Bit 11:0—user watchdog value. (10)
• Bit 12—current state of the user watchdog.
• Bit 16:13—
msm_cs
value of the current state.
• Bit 31:17—reserved.
5 R 32
• Bit 3:0—previous state application 1 reconfiguration source
value.
• Bit 7:4—
msm_cs
value of the previous state application 1.
• Bit 31:8—reserved.
6 R 32
• Bit 3:0—previous state application 2 reconfiguration source
value.
• Bit 7:4—
msm_cs
value of the previous state application 2.
• Bit 31:8—reserved.
7 R 32
• Bit 0—
config_sel_overwrite
value from the input register.
• Bit 1—
config_sel
value of the input register. (11)
• Bit 31:2—reserved.

(10) You can only read the 12 most significant bit of the 29 bit user watchdog value using Dual Configuration
IP Core.
(11) Reads the
config_sel
of the input register only. It will not reflect the physical CONFIG_SEL pin setting.
