Type Description

rw
TTOFF Delay Value (safe turn-off).
This bit field defines the TTOFF delay for a safe turn-off
(in OSC2 clock cycles). Writing 00_H to this field
deactivates the TTOFF function for regular turn-off. if
used, a minimal value of at least A_H has to be
programmed.
Note:
1. In OPM5 and OPM6, it is recommended to have this
bit field programmed to 0_H.
2. In OPM4, when safe two level turn off is used, bit field
STVAL shall be programmed with a higher value than
field SRTTOF.RTVAL.

rw
TTOFF Plateau voltage (safe turn-off)
This bit field defines the TTOFF plateau voltage for safe
turn-off sequences. Coding is identical to
PCTRL2.GPOF.
Note: In OPM4, bit field GPS shall be programmed with a
value smaller or equal than field PCTRL2.GPOF.
