*WRITE BITS (Status/Control Register)

 

 

 

bit 0

R

Writing a "1" to this bit resets the digitizer to the power-on state. You must set bit 0 back

 

 

to a logical "0" before resuming normal operations of the module.

 

 

 

bit 1

S

“1” inhibits sysfail, “0” does not inhibit sysfail.

 

 

 

bit 6

E

“1” disables error reporting LED, “0” enables error reporting LED (front panel).

 

 

 

bit 7

F

“1” disables Flash ROM “write”, “0” enables Flash ROM “write”.

 

 

 

bit 12

A24

“1” sets A24 space as all FIFO, “0” sets A24 space as broken up.

 

 

 

bit 13

MOT-INTEL

“1” sets Motorola format for reading ordering, “0” sets Intel format for reading ordering.

 

 

 

bit 15

A

“1” enables A32 decoding, “0” enables A24 decoding.

 

 

 

 

 

**READ BITS (Status/Control Register)

 

 

 

bit 0

R

Reset Status; "1" = module reset, "0" = normal operation.

 

 

 

bit 1

S

SYSFAIL inhibit; “1” = inhibited, “0” = not inhibited.

 

 

 

bit 2

P

Passed; “1” = passed, “0” = failed.

 

 

 

bit 3

RDY

Ready; “1” = A32 decoding enabled, “0” = A24 decoding enabled.

 

 

 

bits 4 & 5

Arm

Bit 4 is “1” for 1 msec after a range/filter change then returns to “0”, bit 5 is “1”

 

Delay

for 30 msec after range/filter change then returns to “0”.

 

 

 

bit 6

E

Error; “1” disables front panel error LED, “0” enables front panel error LED.

 

 

 

bit 7

F

Flash ROM; “1” disables Flash ROM “write”, “0” enables Flash ROM “write”.

 

 

 

bits 8, 9,

Memory

Memory Size; “000” = 4 MBytes, “001” = 8 MBytes, “010” = 16 MBytes, “011” = 32 MBytes,

and 10

Size

“100” = 64 MBytes, “101” = 128 MBytes.

 

 

 

bit 12

A24

“1” sets A24 space as all FIFO, “0” sets A24 space as broken up.

 

 

 

bit 13

MOT-

“1” = Motorola big endian byte swapping, “0” = Intel little endian byte swapping.

 

INTEL

 

 

 

 

bit 14

M

MODID bit; if the bit is "0", module has been selected.

 

 

 

bit 15

A

A24/A32 enable; “1” = A32 decoding enabled, “0” = A24 decoding enabled.
