Value Description
Reserved
When a trip event occurs the following action is taken on output EPWMxB. Which trip-zone pins
can cause an event is defined in the TZSEL register.
00 High impedance (EPWMxB = High-impedance state)
01 Force EPWMxB to a high state
10 Force EPWMxB to a low state
11 Do nothing, no action is taken on EPWMxB.
When a trip event occurs the following action is taken on output EPWMxA. Which trip-zone pins
can cause an event is defined in the TZSEL register.
00 High impedance (EPWMxA = High-impedance state)
01 Force EPWMxA to a high state
10 Force EPWMxA to a low state
11 Do nothing, no action is taken on EPWMxA.
