12-16 Output Functions
Bit 13 of word 200 is the battery status bit. It can have one of the following values:
•
0 - Battery is good
•
1 - Battery is low
Word integrity is guaranteed during this transfer. File integrity is not. Handshaking
bits can be used in your application program to provide file integrity.

CALL 57 – Transfer
BASIC Output Buffer to
CPU M1 File Purpose
Use CALL 57 to transfer up to 64 words starting at word 100 from the module
output buffer to the CPU M1 file starting at word 0. This routine has one input
argument and one output argument. The input argument is the number of words
to be transferred (1 to 64). If the number is not within the range 1 to 64, no
transfer occurs and the output argument is set to 10.
If the input argument is a valid number, then the output argument is the status of
the Logic Processor. It can have one of the following values:
•
0 - Successful transfer, SLC processor in Run mode
•
1- Successful transfer, SLC processor in Program mode
•
2 - Successful transfer, SLC processor in Test mode
•
10 - Illegal length specified
•
11 - SLC processor does not support this capability
Word integrity is guaranteed during this transfer. File integrity is not. Handshaking
bits can be used in your application program to provide file integrity.
