• Bit 9—Down-Count Start 8J (DST8J): Starts down-counter 8J (DCNT8J).
Bit 9: DST8J
0
1
Description
DCNT8J is halted
(Initial value)
[Clearing conditions]
When the DCNT8J value underflows, or on channel 2 (GR2B) compare-
match
DCNT8J counts
[Setting conditions]
• One-shot pulse function: Set by user program (DCNT8J ≠ H'0000)
• Offset one-shot pulse function: Set on OCR2B compare-match (DCNT8J
≠ H'0000 or reload possible) or by user program (DCNT8J ≠ H'0000)
• Bit 8—Down-Count Start 8I (DST8I): Starts down-counter 8I (DCNT8I).
Bit 8: DST8I
0
1
Description
DCNT8I is halted
(Initial value)
[Clearing conditions]
When the DCNT8I value underflows, or on channel 2 (GR2A) compare-match
DCNT8I counts
[Setting conditions]
• One-shot pulse function: Set by user program (DCNT8I ≠ H'0000)
• Offset one-shot pulse function: Set on OCR2A compare-match (DCNT8I ≠
H'0000 or reload possible) or by user program (DCNT8I ≠ H'0000)
• Bit 7—Down-Count Start 8H (DST8H): Starts down-counter 8H (DCNT8H).
Bit 7: DST8H
0
1
Description
DCNT8H is halted
(Initial value)
[Clearing conditions]
When the DCNT8H value underflows, or on channel 1 (GR1H or OCR1)
compare-match
DCNT8H counts
[Setting conditions]
• One-shot pulse function: Set by user program (DCNT8H ≠ H'0000)
• Offset one-shot pulse function: Set on OCR1 compare-match or GR1H
compare-match, or by user program (DCNT8H ≠ H'0000)
