3–2 TZB 0-3h 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 (Section 15.2.4.5.1).
0 High impedance (EPWMxB = High-impedance state)
1h Force EPWMxB to a high state
2h Force EPWMxB to a low state
3h Do nothing, no action is taken on EPWMxB.
1–0 TZA 0-3h 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 (Section 15.2.4.5.1).
0 High impedance (EPWMxA = High-impedance state)
1h Force EPWMxA to a high state
2h Force EPWMxA to a low state
3h Do nothing, no action is taken on EPWMxA.
15.2.4.5.3 Trip-Zone Enable Interrupt Register (TZEINT)
The trip-zone enable interrupt register (TZEINT) is shown in Figure 15-87 and described in Table 15-81.

2 OST Trip-zone One-Shot Interrupt Enable
0 Disable one-shot interrupt generation
1 Enable Interrupt generation; a one-shot trip event will cause a EPWMxTZINT interrupt.
1 CBC Trip-zone Cycle-by-Cycle Interrupt Enable
0 Disable cycle-by-cycle interrupt generation.
1 Enable interrupt generation; a cycle-by-cycle trip event will cause an EPWMxTZINT interrupt.
