SMI Status
The SMI Status Register provides status information for signals capable of triggering the
CPI_SMI# input to the processor.
1
WDOG_NMI_MSK
1
Watchdog NMI Mask—blocks (masks) the MV64460
Watchdog NMI signal from asserting the CPU_SMI# (NMI
is signaled through the SMI# input).
0 = enable WDOG NMI signal
1 = disable (mask) WDOG NMI signal
0
GPIO_NMI_MSK
1
NMI on GPIO15 Interrupt Mask—blocks (masks) the NMI
signal on the GPIO15 line.
0 = enable SMI
1 = disable (mask) SMI

nal status.
0 = DEG# signal is de-asserted
1 = DEG# signal is asserted
2
FAL_STAT
1
FAL# signal Status—indicates the backplane FAL# signal
status.
0 = FAL# signal is de-asserted
1 = FAL# signal is asserted

WDOG_NMI_STAT
1
Watchdog NMI Status—indicates the MV64460 Watch-
dog NMI signal status.
0 = WDOG NMI signal is de-asserted
1 = WDOG NMI signal is asserted
0
GPIO_NMI_STAT
1
NMI on GPIO15 Input Active (if enabled)—indicates the
NMI signal is active on the GPIO15 line.
0 = input inactive
1 = input active
