1.6.1 CLKMODE Multiplier
TheC6413/C6418 has a number of clock multiplier modes that are selected at reset by
sampling the CLKMODE[3-0] pins. These pins can be configured with the on-board
jumpers. The jumper configuration is shown in the table below.
Note: * default on C6413
** default on C6418
1.6.2 CLKINSEL
The C6413/C6418 has the option of using an external clock oscillator or internal
oscillator to operate the PLL which controls the internal CPU clock. This clock is input
is selected at reset by the CLKINSEL pin. The EVM provides a configuration jumper to
select either the internal or external oscillator which controls the PLL. When CLKINSEL
is high (installed) AECLKIN is selected for PLL logic. When CLKINSEL is low
(removed) the internal oscillator controls the PLL clock. On theC6413/C6418 EVM
AECLKIN is driven by an external 25 Mhz oscillator, the internal oscillator is connected
to the external crystal which is 25 Mhz
