Hello,
Clarification, the default condition of the SPI_3WIRE_DIS register is "0x1 = 3-wire SPI readback disabled"
By this I expect that 4-wire readback is the default?
However, none of the GPIO pins default to 0xF = SPI Readback Data (SDO)
Is it expected that the after POR the desired GPIO pin would need to be set to 0xF = SPI Readback Data (SDO) before the 4-wire readback will be active?
Thanks,
Jon
Thank you Noel.
I only read the R54 table and misread that the function was set in R57. Thanks for the clarification.
