1 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 JPC5604B, the
spec value of tCSC will be attained only if TDSPI x PSSCK x CSSCK > tCSC .
3 The maximum value is programmable in DSPI_CTARn [PASC] and DSPI_CTARn [ASC]. For JPC5604B, the spec
value of tASC will be attained only if TDSPI x PASC x ASC > tASC.
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.
