Peripheral operating requirements and behaviors
1. Typical values assume VREGIN = 5.0 V, Temp = 25 °C unless otherwise stated.
2. Operating in pass-through mode: regulator output voltage equal to the input voltage minus a drop proportional to I
6.8.4 DSPI switching specifications (limited voltage range)
The DMA Serial Peripheral Interface (DSPI) provides a synchronous serial bus with
master and slave operations. Many of the transfer attributes are programmable. The tables
below provide DSPI timing characteristics for classic SPI timing modes. Refer to the
DSPI chapter of the Reference Manual for information on the modified transfer formats
used for communicating with slower peripheral devices.
1. The delay is programmable in SPIx_CTARn[PSSCK] and SPIx_CTARn[CSSCK].
2. The delay is programmable in SPIx_CTARn[PASC] and SPIx_CTARn[ASC].
