(R/W) Determines the reset
duration
Value Description
Determines the duration between the deactivation of a reset
event (eg. VDD rises above the VBO level, or watchdog expires)
and the NRST pin becoming deactivated
This register determines the reset duration under the following
conditions:
If the DeviceMode register in ADCConfig register is set to 000,
i.e. ‘Normal’ mode, and the SNSE pin is 1 during startup, then
this register determines the reset duration. (if SNSE=0 on
startup, then reset duration is 6 ms, if SNSE is unconnected,
then reset duration is 270 ms)
If the DeviceMode register is set to any other mode, then this
register determines the reset duration irrespective of the SNSE
pin.
Please note that increasing the value of this register in any
mode except normal (DeviceMode=000) causes a reset.
Note that this register may not be changed if the
App-specificFuseWP bit in the WriteProtects register is set
