### Problem Description
I am using SPISlave functionality and WiFiManager lib to config wifi connection. External MCU makes some SPI requests to ESP. All works ok, except that moment, when I am trying to do any SPI request while ESP in STA+AP mode (while it switches to this mode, I believe). I found same issue, but with UART, several years ago: #1073. This "protection from UART interrupts" I found here: https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266WiFi/src/ESP8266WiFiGeneric.cpp#L429
Soon I will try to add `ETS_SPI_INTR_DISABLE()` and enable too and write here about results, but this issue is about another possible problem:
**Maybe we need to block all other unsafe interrupts in same critical sections, not only UART?** There also a plenty of another interrupts, which may cause same issues: https://github.com/esp8266/Arduino/blob/master/tools/sdk/include/ets_sys.h#L128
