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
