Implementation
Timer module frequency
In Timer Mode, the input clock of the timer module is derived from the internal module clock f
CC6
.
By default, the internal module clock f
CC6
is initialized by the iLLDs to run at 100 MHz.
The initialization is done by the function IfxScuCcu_init() that can be found in the iLLD header IfxScuCcu.h .
Starting from this value, it is possible to set the timer module frequency to the following exact values:
100000000 Hz = 100 MHz ( f
CC6
)
50000000 Hz = 50 MHz ( f
CC6
/ 2 )
25000000 Hz = 25 MHz ( f
CC6
/ 4 )
12500000 Hz = 12.5 MHz ( f
CC6
/ 8 )
6250000 Hz = 6.25 MHz ( f
CC6
/ 16 )
3125000 Hz ~ 3 MHz ( f
CC6
/ 32 )
1562500 Hz ~ 1.5 MHz ( f
CC6
/ 64 )
781250 Hz ~ 780 KHz ( f
CC6
/ 128 )
390625 Hz ~ 390 KHz ( f
CC6
/ 256 )
195312.5 Hz ~ 200 KHz ( f
CC6
/ 512 )
97656.25 Hz ~ 100 KHz ( f
CC6
/ 1024 )
48828.12 Hz ~ 50 KHz ( f
CC6
/ 2048 )
24414.06 Hz ~ 25 KHz ( f
CC6
/ 4096 )
12207.03 Hz ~ 12.5 KHz ( f
CC6
/ 8192 )
6103.51 Hz ~ 6 KHz ( f
CC6
/ 16384 )
3051.75 Hz ~ 3 KHz ( f
CC6
/ 32768 )
Note: Any value can be set as frequency parameter, but the software will round up the chosen value to the
nearest higher frequency listed in the above table (e.g. setting timerConfig.base.t12Frequency = 400000
the timer will run at 781250 Hz).
