11. APPENDIX B: COUNTER / TIMER MEMORY ADDRESSES

AND DATA DEFINITIONS

11.1 COUNTER / TIMER 1-BYTE RAM MEMORY DATA

(L) = Lower memory, (U) = Upper memory

The bit assignments below constitute an 8-bit binary number, which needs to be converted to

Hex using a program such a Scientific Calculator under MS Windows Accessories. To change

an Item in Counter

Timer RAM Memory, write the converted Hex value to the Hex Address

shown in the left column. To change an Item in Nonvolatile Memory, go to table 11.4, read the

existing two-byte word (MS byte and LS byte) from the Counter

Timer for the Hex Address

which includes the Item to be changed, edit the MS or LS byte as appropriate, and write the

edited word back to the Hex Address.
