0
1
Description
DCNT8F is halted
(Initial value)
[Clearing condition]
When the DCNT8F value underflows, or on channel 1 (GR1F or OCR1)
compare-match
DCNT8F counts
[Setting conditions]
• One-shot pulse function: Set by user program (DCNT8F ≠ H'0000)
• Offset one-shot pulse function: Set on OCR1 compare-match or GR1F
compare-match, or by user program (DCNT8F ≠ H'0000)
