For Infineon XC878L-16FF — Capture/Compare Unit 6 (CCU6)
Simulation support for this peripheral or feature is comprised of:
- Dialog boxes which display and allow you to change peripheral configuration.
These simulation capabilities are described below.
CCU6 Capture Compare Dialog

the next value to be stored by the CCU into CC6xR.

the dead-time control bit setting below:
DTM (Dead-Time) is an 8-bit down count that defines the
delay between passive to active states for the Timer 12 compare
DTEx (Dead-Time Enable Bits) are set to allow dead-time
generation for each capture/compare channel (0-2).
DTRx (Dead-Time Run Indication Bits) are set when a
dead-time counter is non-zero.
