• Bit 9—Down-Count Start 8J (DST8J): Starts down-counter 8J (DCNT8J).

Bit 9: DST8J

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

Description

DCNT8I is halted

• Bit 7—Down-Count Start 8H (DST8H): Starts down-counter 8H (DCNT8H).

Bit 7: DST8H

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
