14.10 DMA Support.
14.11 Timer/Counter Commands
8077H–AVR–12/09
The interrupt flags can be used to trigger DMA transactions.
transfer triggers available from the T/C, and the DMA action that will clear the transfer trigger.
For more details on using DMA refer to
Table 14-2.
A set of commands can be given to the Timer/Counter by software to immediately change the
state of the module. These commands give direct control of the Update, Restart, and Reset
signals.
An update command has the same effect as when an update condition occurs. The update com-
mand is ignored if the Lock Update bit is set.
The software can force a restart of the current waveform period by issuing a restart command. In
this case the Counter, direction, and all compare outputs are set to zero.
A reset command will set all Timer/Counter registers to their initial values. A reset can only be
given when the Timer/Counter is not running (OFF).
