Dear Nordic team
I have the following code for testing the SPIM function of nRF52832.
NRF_SPIM1->EVENTS_END = 0U;
NRF_SPIM1->ENABLE = 0;
NRF_SPIM1->ENABLE = (SPIM_ENABLE_ENABLE_Enabled << SPIM_ENABLE_ENABLE_Pos);
dataout= 0x05;
NRF_SPIM1->EVENTS_END = 0;
NRF_SPIM1->TXD.PTR = (uint32_t)&dataout;
NRF_SPIM1->TXD.MAXCNT = 1;
NRF_SPIM1->RXD.PTR = (uint32_t)&datain;
NRF_SPIM1->RXD.MAXCNT = 1;
NRF_SPIM1->TASKS_START = 1;
while (!NRF_SPIM1->EVENTS_END);
After running the code and capturing the signal, we found that there are extra clock pulse appears after sending the data.
Device: nRF52832
SDK 15.3.0
softdevice: S332 v6.1.1
Would you help?
Best Regards
