Hello, I found that after using SPIM I have forever additional over consumption (additional 400-500uA). It was solved here in forum
And there is errata 89
[edit] I thought I was not using GPIOTE but I was using GPIOTE through another SPI workaround for clocking extra byte out.
But part of my questions are still valid:
Can you also add into errata that it also affect SPI block (because it is written that it affect TWI block)?
Also can you add to errata that you need to reinicialize SPI? For my case correct workaround seems to be:
void twi_spi_over_consumption_workaround(){
nrf_drv_spi_uninit(&g_spi);
*(volatile uint32_t *)0x40003FFC = 0;
*(volatile uint32_t *)0x40003FFC = 0;
*(volatile uint32_t *)0x40003FFC = 1;
// SPI reconfiguration
APP_ERROR_CHECK(nrf_drv_spi_init(&g_spi, &g_spi_config, spi_event_handler));
}
