Data Sheet
.RSS2, RSS1
The reset sources and the SDS2 functionality for the RSTO/SDS2 output pin can be
selected according to the table below.
For RSS = ’00’ no reset is generated at pin RSTO/SDS2.
For RSS = ’01’ a serial data strobe is output at pin RSTO/SDS2 (see chapter 2.2.3).
For RSS = ’10’ an External Awake or a change in the downstream C/I0 channel
For RSS = ’11’ the watchdog function is enabled (see chapter 6.1).
A hardware reset or a reset generated by the undervoltage detection is always output at
pin RSTO/SDS2.
After a reset pulse and the corresponding interrupt (WOV or CIC) have been generated
by the SCOUT the actual reset source can be read from the ISTA.
