Location monitor 1 is configured to monitor double-byte
accesses to the supervisor short I/O address $00F2, and singlebyte accesses to the short I/O address $00F3. When cleared,
LM1 indicates that an access to address $00F2 or $00F3 was
detected. At such a time, utility interrupt level 4 is requested (if
the interrupt is enabled). LM1 is set when the interrupt is
acknowledged or when software writes a 1 to it. This bit is set to
1 by SYSRESET. See Note below.
Bit 6 Location monitor 2 is configured to monitor double-byte
accesses to the supervisor short I/O address $00F4, and singlebyte accesses to the short I/O address $00F5. When cleared,
LM2 indicates that an access to address $00F4 or $00F5 was
detected. LM2 is set when software writes a 1 to it. This bit is set
to 1 by SYSRESET. See Note below.Location monitor 3 is configured to monitor double-byte
accesses to the supervisor short I/O address $00F6, and singlebyte accesses to the short I/O address $00F7. When cleared,
LM3 indicates that an access to address $00F6 or $00F7 was
detected. LM3 is set when software writes a 1 to it. This bit is set
to 1 by SYSRESET. See Note below.The GCSR Base Address Configuration Register must
be programmed to allow the GCSR set of registers to
respond to VMEbus accesses for this function to be
enabled.
The VMEbus master that executes the location monitor
cycle must generate the DTACK signal to terminate the
cycle. The SIGLP control signal allows other VMEbus masters to
interrupt the MC68030. SIGLP can only be set from the
VMEbus. It can only be cleared by the MC68030. When a
VMEbus master sets SIGLP to a 1, the VMEchip requests a level
1 interrupt to the MC68030 (if such interrupts are enabled). The
interrupt request remains until the MC68030 writes a 1 to it.
This bit is cleared by SYSRESET. See Note 1 below.
Bit 1 The SIGHP control signal allows other VMEbus masters to
interrupt the MC68030. SIGHP can only be set from the
VMEbus. It can only be cleared by the MC68030. When a
VMEbus master sets SIGHP to a 1, the VMEchip requests a level
5 interrupt to the MC68030 (if such interrupts are enabled). The
interrupt request remains until the MC68030 writes a 1 to it.
This bit is cleared by SYSRESET. See Note 1 below.
Bit 4 BRDFAIL is a reflection of the BRDFAIL* input/output signal
line. The status bit is set to 1 whenever the signal line is
activated by either the VMEchip, or by a watchdog time-out
