1/DCLK. The DSP clock can be defined as follows:
External CLKIN Mode:
DCLK == CLKIN/4 before and during boot
DCLK == CLKIN after boot
Internal Clock Mode:
DCLK == 10MHz before and during boot, i.e. DCLKP == 100ns
DCLK == 65 MHz after boot, i.e. DCLKP == 15.4ns
It should be noted that DCLK for the internal clock mode is application specific. The application code
users guide should be checked to confirm DCLK for the particular application.
