• Bit 6—Down-Count Start 8G (DST8G): Starts down-counter 8G (DCNT8G).
Bit 6: DST8G
0
1
Description
DCNT8G is halted
(Initial value)
[Clearing conditions]
When the DCNT8G value underflows, or on channel 1 (GR1G or OCR1)
compare-match
DCNT8G counts
[Setting conditions]
• One-shot pulse function: Set by user program (DCNT8G ≠ H'0000)
• Offset one-shot pulse function: Set on OCR1 compare-match or GR1G
compare-match, or by user program (DCNT8G ≠ H'0000)
