Specify the clock rate of the CPU (SYSCLKOUT) in nS.
|
||
|
|
|
||
|
|
Take into account the input clock frequency and the PLL multiplier
|
||
|
|
selected in step 1.
|
||
|
|
|
||
|
|
Use one of the values provided, or define your own.
|
||
|
|
The trailing L is required tells the compiler to treat
|
||
|
|
the number as a 64-bit value.

Only one statement should be uncommented.

Example 1:150 MHz devices:
|

|
|
CLKIN is a 30MHz crystal.

In step 1 the user specified PLLCR = 0xA for a
|
||
|
|
150Mhz CPU clock (SYSCLKOUT = 150MHz).
|
||
|
|
|
||
|
|
In this case, the CPU_RATE will be 6.667L
|
||
|
|
Uncomment the line: #define CPU_RATE 6.667L

Example 2: 100 MHz devices:
|
||
|
|
CLKIN is a 20MHz crystal.
|

|
|
||
|
|
In step 1 the user specified PLLCR = 0xA for a
|
||
|
|
100Mhz CPU clock (SYSCLKOUT = 100MHz).
|
||
|
|
|
||
|
|
In this case, the CPU_RATE will be 10.000L
