Bit 8 DTEN: Deadtime enable
This bit enables the deadtime insertion on output 1 and output 2.
0: Output 1 and output 2 signals are independent.
1: Deadtime is inserted between output 1 and output 2 (reference signal is output 1 signal generator)
Note: This parameter cannot be changed once the timer is operating (TxEN bit set) or if its outputs are
enabled and set/reset by another timer.
Bit 7 DIDL1: Output 1 deadtime upon burst mode idle entry
This bit delays the idle mode entry by forcing a deadtime insertion before switching the outputs to
their idle state. This setting only applies when entering the idle state during a burst mode operation.
0: The programmed idle state is applied immediately to the output 1
1: Deadtime (inactive level) is inserted on output 1 before entering the idle mode. The deadtime
value is set by DTRx[8:0].
Note: This parameter cannot be changed once the timer x is enabled.
DIDL=1 is set only if one of the outputs is active during the burst mode (IDLES=1), and with
positive deadtimes (SDTR/SDTF set to 0).
Bit 6 CHP1: Output 1 chopper enable
This bit enables the chopper on output 1.
0: Output signal is not altered
1: Output signal is chopped by a carrier signal
Note: This parameter cannot be changed once the timer x is enabled.
Bits 5:4 FAULT1[1:0]: Output 1 fault state
These bits select the output 1 state after a fault event
00: No action: the output is not affected by the fault input and stays in run mode.
01: Active
10: Inactive
11: High-Z
Note: This parameter cannot be changed once the timer x is enabled (TxCEN bit set), if FLTENx bit is
set or if the output is in FAULT state.
Bit 3 IDLES1: Output 1 Idle State
This bit selects the output 1 idle state.
0: Inactive
1: Active
Note: This parameter must be set prior to HRTIM controlling the outputs.
Bit 2 IDLEM1: Output 1 Idle mode
This bit selects the output 1 idle mode.
0: No action: the output is not affected by the burst mode operation.
1: The output is in idle state when requested by the burst mode controller.
Note: This bit is preloaded and is changed during runtime, but must not be changed while burst mode
is active.
Bit 1 POL1: Output 1 polarity
This bit selects the output 1 polarity.
0: Positive polarity (output active high)
1: Negative polarity (output active low)
Note: This parameter cannot be changed once the timer x is enabled.
Bit 0 Reserved, must be kept at reset value.
