DMACLRACT
When this bit is set, the DMA requests are cleared when the corresponding DMA channel is active. This enables the timer DMA
requests to be cleared without accessing the timer.
DEBUGRUN
Set this bit to enable timer to run in debug mode.
QDM
This bit sets the mode for the quadrature decoder.
OSMEN
Enable/disable one shot mode.
SYNC
When this bit is set, the Timer is started/stopped/reloaded by start/stop/reload commands in the other timers
Reserved
MODE
These bit set the counting mode for the Timer. Note, when Quadrature Decoder Mode is selected (MODE = 'b11), the CLKSEL is
don't care. The Timer is clocked by the Decoder Mode clock output.
Reserved
STOP
Write a 1 to this bit to stop timer
