Hi everyone,
Are QSPI "3-pin write" and "4-pin write" pins and functions are the same?
The functions are as follows, so I think the same.
3-pin spi write & 4-pin spi write
- qspi1_d0 : spi data output
- qspi1_d1 : not used
- qspi1_d2 : not used
- qspi1_d3 : not used
- qspi1_sclk : clock for the external spi device
- qspi1_cs0 : external spi device chip-select0
Best regards,
Sasaki
