APPENDIX A: SNAP ETHERNET-BASED BRAIN MEMORY MAP
Digital Bank Write—Read/Write
NOTE: To clear counters and latches, use the “Digital Read and Clear” area on page 132.
Although this area is read/write, you would normally write to it. For help in formatting data, see
“Mask Data” on page 41. For general information on using counters, see page 21.
Starting Address Length Type Description
FFFF F050 0000 8 M Turn on (mask)
FFFF F050 0008 8 M Turn off (mask)
FFFF F050 0010 8 M Activate counters (mask)
FFFF F050 0018 8 M Deactivate counters (mask)
Last valid address for this area: FFFF F050 001F
Analog Bank Read—Read Only
For help in interpreting data, see “IEEE Float Data” on page 43.
Starting Address Length Type Description
FFFF F060 0000 100 F Analog data (float—Engineering Units)
FFFF F060 0100 100 F Analog data (float—counts)
FFFF F060 0200 100 F Analog Min Value (float—Engineering Units)
FFFF F060 0300 100 F Analog Max Value (float—Engineering Units)
Last valid address for this area: FFFF F060 03FF
Analog Bank Write—Read/Write
Although this area is read/write, you would normally write to it. For help in formatting data, see
“IEEE Float Data” on page 43.
Starting Address Length Type Description
FFFF F070 0000 100 F Analog output (float—Engineering Units)
FFFF F070 0100 100 F Analog output (float—counts)
Last valid address for this area: FFFF F070 01FF
