    The transfer clock frequency for 3-wire serial I communication can be calculated by the following expressions.
    (1) For Master
    (Transfer clock frequency) = {Operation clock (fMCK) frequency of target channel} ÷ (SDRmn[15:9] + 1) ÷ 2 [Hz]
    (2) For Slave
    (Transfer clock frequency) = {Frequency of serial clock (fSCK) supplied by master}Note [Hz]
    Note :The permissible maximum transfer clock frequency is fMCK/6.
    Remark :The value of SDRmn[15:9] is the value of bits 15 to 9 of serial data register (SDRmn) (0000000B to 1111111B) and therefore is 0 to 127. The operation clock (fMCK) is determined by serial clock select register m (SPSm) and bit 15 (CKSmn) of serial mode register mn (SMRmn).

    Hi,

    I have attached an example project on RA2L1 for your reference done on FSP2.3.0. Please update it to latest version if incase you use this example.

    You would have to edit the linker script, to change the start address in Code flash of the application, however the file memory_regions.ld is an auto-generated file so any edits are overwritten. Make a copy of memory_regions.ld and give it a different name, e.g. memory_regions_application.ld.

     

    and change the reference from “memory_regions.ld” to the name of the copy of the file you made, at the top of fsp.ld :-

     

    /*

    Linker File for Renesas FSP

    */

     

    INCLUDE memory_regions_application.ld

     

    in the file memory_regions_application.ld change the start address and size of the code flash :-

     

    FLASH_START = 0x00008000;

    FLASH_LENGTH = 0x38000;

     

    and then in the debug configuration for the application, in the “Run Commands”  at the bottom of the Startup tab set the Program counter, Initial Stack pointer and VTOR register to the moved location :-

     

    set $pc = *0x00008004

    set $sp = *0x00008000

    set {int}0xE000ED08 = 0x00008000
