This is an unfortunate miss from our side, the s132 lacks API for setting the GPREGRET2 register. However, it is possible to workaround this by disabling the MWU when you want to access it:

 #define TEST_UNPROTECT_POWER \

NRF_MWU->PREGION[0].SUBS &= ~(MWU_PREGION_SUBS_SR0_Include << MWU_PREGION_SUBS_SR0_Pos)

#define TEST_REPROTECT_POWER \

 NRF_MWU->PREGION[0].SUBS |= (MWU_PREGION_SUBS_SR0_Include << MWU_PREGION_SUBS_SR0_Pos) 

This has already been reported internally.

@Vidar Berg : please, could you confirm that the workaround above is the still valid and it is the right way to use GPREGRET2 with softdevice 132 v2.0.0? Thank you
