1. This value of this parameter is dependent upon the external device delays and the other parameters mentioned in this
table.
Δ 2. The maximum value is programmable in DSPI_CTARn [PSSCK] and DSPI_CTARn [CSSCK]. For SPC564B74 and
SPC56EC74, the spec value of t_CSC will be attained only if T_DSPI x PSSCK x CSSCK > t_CSC .
Δ 3. The maximum value is programmable in DSPI_CTARn [PASC] and DSPI_CTARn [ASC]. For SPC564B74 and
SPC56EC74, the spec value of t_ASC will be attained only if T_DSPI x PASC x ASC > t_ASC.
4. The parameter value is obtained from t_SUSS and t_SUO for slave.
5. This number is calculated assuming the SMPL_PT bitfield in DSPI_MCR is set to 0b00.
6. For DSPI1, the Data Hold Time for Outputs in Master (MTFE = 0) is −2 ns.
7. For DSPI1, the Data Hold Time for Outputs in Master (MTFE = 1, CPHA = 0) is −2 n.
8. For DSPI1, the Data Hold Time for Outputs in Master (MTFE = 1, CPHA = 1) is −2 ns.
