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.
