4 Dead-Band Control

The dead-band control provides non-overlapping complementary outputs to prevent shoot-through current when the outputs switch. The CWG contains two 6-bit dead-band counters, the CWGx Rising Dead-Band Count (CWGxDBR) and CWGx Falling Dead-Band Count (CWGxDBF) registers. CWGxDBR is used for the rising edge of the input source control in Half Bridge mode or for reverse direction change dead band in Full Bridge mode. CWGxDBF is used for the falling edge of the input source control in Half Bridge mode or for forward direction change dead band in Full Bridge mode.

Dead band is timed by counting CWG clock periods from zero up to the value in the rising or falling dead-band counter registers.
