TYPICAL
Once RINT is generated the code begins execution at the
label RINT. This code stores the D
OUT
word from the
LTC1198 in the ACC and then stores it in location 200 hex.
The data appears in location 200 hex right-justified as
shown in Figure 19. The code is set up to continually loop,
so at this point the code jumps to label TXRX and repeats
from here.
