Technical Data

NOTE:
Before changing a channel function by writing to the MSxB or MSxA bit,
set the TSTOP and TRST bits in the TIM status and control register
(TSC).
ELSxB and ELSxA — Edge/Level Select Bits
MSxB:MSxA
When ELSxB:ELSxA = 0:0, this read/write bit selects the initial output
level of the TCHx pin. See
When channel x is an input capture channel, these read/write bits
control the active edge-sensing logic on channel x.
When channel x is an output compare channel, ELSxB and ELSxA
control the channel x output behavior when an output compare
occurs.
When ELSxB and ELSxA are both clear, channel x is not connected
to port D, and pin PTDx/TCHx is available as a general-purpose I/O
pin.
