EXECUTION
N blocs transfert :
- direct addressing (Li < 80H, Di and Si < 8000H).
- indirect addressing (Li >= 80H, Di and Si >= 8000H).
In this case the parameters are placed at the addresses :
Li - 80H = for the length
Di - 8000H = for the destination address
Si - 8000H = for the source address
The indirection is done each time that the MSB of the new address = 1
(value > 80H ou > 8000H)
like this each parameter has his proper indirection level.
WARNING : The board makes no control about the addresses !
COMMENTS
Parameters control :
Example on Li (evalable for Si and Di with 8000H) :
Li < 80H : Li = length
Li >= 80H
(Li-80H) < 80H : (Li-80H) = length
(Li-80H) >= 80H
((Li-80H)-80H) < 80 : ((Li-80H)-80H) = length
((Li-80H)-80H) >= 80
etc .........
SYMBOLS DEFINITION LIMITS
L Length or pointer to the length (if > 80H).
DpF/Dpf Address or pointer to the source (si > 8000H)
ou D
SpF/Spf Address or pointer to the destination
ou S (if >8000H).
LS jump line number after transfert(s) (optional)
82H
LMOV.BI
EXAMPLE
Direct transfert an area of 10 bytes starting at the address 810H to the address 820H and
an area with parameters stored at the address 800H (length), 881H,882H (destination),
883H et 884H (source).
After the transfert, the program continues on the next line (LS is missing).
