SET SYSTEM
(@)SYS(49)
(CPU11-E)
SYS(49)
P
–––
–––
Used to either control certain operating
parameters, or to execute the system
commands that can be executed from the
AR area.
The contents of the leftmost 8 bits (i.e., bits
08 to 15) of P determine which function
SYS(49) will have. If they contain A3, then
bit 00 specifies whether the battery will be
checked, and bit 07 specifies whether I/O
status will be maintained on start up. Bit 06
specifies whether the Force Status Hold
Bit is set.
To be effective SYS(49) must be pro-
grammed at address 00001 with LD AR
1001 at address 00000.
