3.1.2
System Control Register
The MVME7100ET has a System Control Register that provides general board control bits.
Core 1 OFFSET
Core 1 Low Memory Offset. This bit reflects the current state of Core 1 Low
Memory Offset switch. A cleared condition indicates the switch is off. A set
condition indicates the switch is on. When this switch is on, real address A in the
range of 0 to 256 MBytes-1 is translated to address A +256 MBytes. When this
switch is off, the address is not translated.
PMC133
PMC133. This bit reflects the current state of the PMC 133 MHz switch. A
Cleared condition indicates the switch is off. A set condition indicates the switch
is on. When this switch is on, the maximum PMC clock frequency is 133 MHz.
When this switch is off, the maximum PMC clock frequency is 100 MHz.
MASTER WP
MASTER WP. This bit reflects the current state of the MASTER WP switch. A
cleared condition indicates the switch is off. A set condition indicates the switch
is on. When this switch is on, the NOR FLASH, NAND FLASH, MRAM and I
2
C
EPROMs are write protected. When this switch is off, NOR FLASH, NAND FLASH,
MRAM and I
2
C EPROMs are not write protected by this function. Other switches
and control bits may write protect individual devices.
SW8
SW8. This bit reflects the current state of SW8. A cleared condition indicates the
switch is off. A set condition indicates the switch is on.
