Remarks
*1: _{tCSSU=SCSTR:CSSU[7:0] x serial chip select timing operating clock}
*2: _{tCSHD=SCSTR:CSHD[7:0] x serial chip select timing operating clock}
*3: _{tCSDS=SCSTR:CSDS[15:0] x serial chip select timing operating clock}
For details on ^*1, ^*2, and ^*3 above, see the hardware manual.
*4 tCLK_LCPnA n=0:ch.0 to ch.4, n=1:ch.8 to ch.12
Notes:
− This is the AC characteristic in CLK synchronized mode.
− CL is the load capacitance applied to pins during testing.
− The maximum baud rate is limited by the internal operating clock used and other parameters.
For details, see the hardware manual.
