N2HET1-N2HET2 Interconnections
In some applications the N2HET resolutions must be synchronized. Some other applications require a
single time base to be used for all PWM outputs and input timing captures.
The N2HET provides such a synchronization mechanism. The Clk_master/slave (HETGCR.16) configures
the N2HET in master or slave mode (default is slave mode). A N2HET in master mode provides a signal
to synchronize the prescalers of the slave N2HET. The slave N2HET synchronizes its loop resolution to
the loop resolution signal sent by the master. The slave does not require this signal after it receives the
first synchronization signal. However, anytime the slave receives the re-synchronization signal from the
master, the slave must synchronize itself again..
