This value of this parameter is dependent upon the external device delays and the other parameters mentioned in this table. 2. The maximum value is programmable in DSPI_CTARn [PSSCK] and DSPI_CTARn [CSSCK]. For SPC564B74 and SPC56EC74, the spec value of tCSC will be attained only if TDSPI x PSSCK x CSSCK > Δt CSC . 3. The maximum value is programmable in DSPI_CTARn [PASC] and DSPI_CTARn [ASC]. For SPC564B74 and SPC56EC74, the spec value of tASC will be attained only if TDSPI x PASC x ASC > Δt ASC. 4. The parameter value is obtained from tSUSS and tSUO 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. Table 50. DSPI timing (continued) Spec Characteristic Symbol Unit Min Max |
