Now, I want to know that which clock is used for DSPI's protocol clock in MPC5744.
Could anyone teach me it?
In the Figure 2-8 at Page 116(Page 117 in the PDF file) in MPC5744P Reference Manual(REV6.1)(https://www.nxp.com/docs/en/reference-manual/MPC5744PRM.pdf), the PBRIDGEx_CLK are supplied to DSPI(4).
And the word "Protocol Clock" is nothing in the DSPI(4) box.
The maximum frequency of PBRIDGE_0, PBRIDGE_1 is defined to 50MHz in the Table 13-2 in Page 339(Page 701 in the PDF file ).
But the fp(the protocol clock) is described with 100MHz or 20MHz as the example in the Table 49-5 at Page 1609(Page 1971 in the PDF file).
Is the other clock used for the protocol clock of DSPI?
