(1) For all boot modes that default to DSPBOOTADDR = 0x0010 0000 (i.e., all boot modes except the EMIFA ROM Direct Boot,
BOOTMODE[3:0] = 0100, FASTBOOT = 0), the bootloader code disables all C64x+ cache (L2, L1P, and L1D) so that upon exit from the
bootloader code, all C64x+ memories are configured as all RAM. If cache use is required, the application code must explicitly enable the
cache. For more information on the bootloader, see the Using the TMS320C642x Bootloader Application Report (literature number
SPRAAK5).
(2) The PLL MODE for Non-Fastboot Modes is fixed as shown in this table; therefore, the PLLMS[2:0] configuration pins have no effect on
the PLL MODE.
(3) I2C Boot (BOOTMODE[3:0] = 0101b) is only available if the MXI/CLKIN frequency is between 21 MHz to 30 MHz. I2C Boot is not
available for MXI/CLKIN frequencies less than 21 MHz.
