Figure 134 Dead-Time Generation Block Diagram
Each of the three dead-time counters has its individual dead-time enable bit, DTEx. An enabled dead-time
counter generates a dead-time delaying the passive-to-active edge of the channel output signal. The change
in a State Bit CC6xST is not taken into account while the dead-time generation of this channel is currently in
progress (active). This avoids an unintentional additional dead-time if a State Bit CC6xST changes too early.
A disabled dead-time counter is always considered as passive and does not delay any edge of CC6xST.
Based on the State Bits CC6xST, the Dead-Time Generation Block outputs a direct signal CC6xST and an
inverted signal CC6xST for each compare channel, each masked with the effect of the related Dead-Time
Counters (waveforms illustrated in
).
