ESP31B Q: HW SPI : Pins for MOSI, MISO, SCK , ( CS )

[rudi ;-)]

hi guys

not sure, i puzzle just in time hw pins for SPI and setup procedure.
in first look, i would take

1. GPIO 19 : MOSI
   GPIO 20 : MISO
   GPIO 22 : SCK
   GPIO 21 : CS

but think i am wrong at this.
have we just in time an example in HW SPI / setup steps / little Docu?

thanks!
best wishes
rudi

edit:
i think SPI ( Master/Slave )
are on:

1. GPIO 08 : MOSI ( SD_DATA1, SPID, HS1_DATA1 )
   GPIO 07 : MISO ( SD_DATA0, SPIQ, HS1_DATA0 )
   GPIO 06 : SCK ( SD_CLK, SPICLK, HS1_CLK, U1CTS )
   GPIO 11 : CS ( SD_CMD, SPICS0, HS1_CMD, U1RTS )

there are 3 SPI busses available. The first is the SPI bus that takes care of the FLASH chip and is referred to simply by SPI.
Then there are the other 2 SPI busses (HSPI and VSPI) and while those have default pins, you can attach them to any pin you like.
