• Bit 15—Down-Count Start 8P (DST8P): Starts down-counter 8P (DCNT8P).
Bit 15: DST8P
0
1
Description
DCNT8P is halted
(Initial value)
[Clearing conditions]
When the DCNT8P value underflows, or on channel 2 (GR2H) compare-
match
DCNT8P counts
[Setting conditions]
• One-shot pulse function: Set by user program (DCNT8P ≠ H'0000)
• Offset one-shot pulse function: Set on OCR2H compare-match (DCNT8P
≠ H'0000 or reload possible) or by user program (DCNT8P ≠ H'0000)
• Bit 14—Down-Count Start 8O (DST8O): Starts down-counter 8O (DCNT8O).
Bit 14: DST8O
0
1
Description
DCNT8O is halted

DCNT8O counts
[Setting conditions]
• One-shot pulse function: Set by user program (DCNT8O ≠ H'0000)
• Offset one-shot pulse function: Set on OCR2G compare-match (DCNT8O
≠ H'0000 or reload possible) or by user program (DCNT8O ≠ H'0000)
• Bit 13—Down-Count Start 8N (DST8N): Starts down-counter 8N (DCNT8N).
Bit 13: DST8N
0
1
Description
DCNT8N is halted
(Initial value)
[Clearing conditions]
When the DCNT8N value underflows, or on channel 2 (GR2F) compare-
match
DCNT8N counts
[Setting conditions]
• One-shot pulse function: Set by user program (DCNT8N ≠ H'0000)
• Offset one-shot pulse function: Set on OCR2F compare-match (DCNT8N
≠ H'0000 or reload possible) or by user program (DCNT8N ≠ H'0000)
