(HALT
instruction)
• HALT mode for timer only.
• STOP mode for only releasing KI
(KI/O high-level output or KI/O0 high-level output)
Relationship between HALT
instruction execution and
status flag (F)
HALT instruction not executed when F = 1
POC circuit
• Mask option
• Low level output to RESET pin on detection
• Provided
• Generates internal reset signal on
