Additional Information
• All Condition Flags (ER, CY, Equals, AER, etc.) and instruction conditions will be cleared at the
beginning of a task. Therefore, Condition Flags cannot be read between two tasks.
• Interlocks (e.g., IL and ILC instructions), jumps (e.g., JMP, CJP, and JME instructions), and
subroutines (e.g., SBS, RET, and SBN instructions) must be completed within each individual
task. For example, jumping cannot be performed from one task to another. If subroutines will
be used by more than one tasks, use global subroutines (GSBS(750), GRET(752), or
GSBN(751) instructions).
