UM10360.pdf (Rev 3 - 19 December 2013 & Rev 3.1 -2 April 2014)

referencing Rev 3.1:

Section 25.7.8 MCPWM Dead-time register (MCDT) (page 544)
-------------------------------------------------------------------------------
DTO,DT1,DT2 used when ACMODE = 0
DTO used for all 3 channels when ACMODE = 1
-------------------------------------------------------------------------------
This makes sense because channel 0 timer is used for all 3 channels.

Section 25.7.8 Three phase AC mode (page 550)
--------------------------------------------------------------
ACMODE = 1

The dead-time mode is disabled.
--------------------------------------------------------------

NXP engiineer(s): What gives?

I will tell you what gives. A manual writer only types into a manual what he/she has been told.

The section 25.7.8 comment "The dead-time mode is disabled." is wrong.
