PHIPTOC supports only definite time characteristic.
For a detailed description of timers, see the
features
Table 341: Reset time characteristics supported by different stages
Reset curve type PHLPTOC
(1) Immediate
(2) Def time reset
(3) Inverse reset
The Type of reset curve setting does not apply to PHIPTOC or when
the DT operation is selected. The reset is purely defined by the Reset
delay time setting.
