Hi all,
I am currently configuring Slice 0 and Slice 1 of CCU4 unit for capturing in timer concatenation mode.
As far as I understand, the process is the following:
-Configure Slice 0 as capture, trigger the events for capturing the signals. Timer concatenation bit 0.
-Configure Slice 1 as capture, Timer concatenation bit 1.
However, I am not able to increase Slice 1 timer counter.
According to the RM, once you set the timer concatenation bit to 1 in Slice 1 it should be configured as Slice 0.
Have I misses any step?
In XMCLib this is the process:
/*
* CCU40 - Slice 0 configuration - Capture Conf
*/
/* Initialize the Slice */
XMC_CCU4_SLICE_CaptureInit(SLICE0_PTR, &capture_config);
XMC_CCU4_EnableShadowTransfer(MODULE_PTR, \
(uint32_t)(XMC_CCU4_SHADOW_TRANSFER_SLICE_0| \
XMC_CCU4_SHADOW_TRANSFER_PRESCALER_SLICE_0));
XMC_CCU4_SLICE_Capture0Config(SLICE0_PTR, XMC_CCU4_SLICE_EVENT_0);
XMC_CCU4_SLICE_ConfigureEvent(SLICE0_PTR, XMC_CCU4_SLICE_EVENT_0, &capture_event0_config);
XMC_CCU4_SLICE_Capture1Config(SLICE0_PTR, XMC_CCU4_SLICE_EVENT_1);
XMC_CCU4_SLICE_ConfigureEvent(SLICE0_PTR, XMC_CCU4_SLICE_EVENT_1, &capture_event1_config);
/* Get the CCU4 slice out of idle mode */
XMC_CCU4_EnableClock(MODULE_PTR, SLICE0_NUMBER);
/* Start the CCU4 Timer */
XMC_CCU4_SLICE_StartTimer(SLICE0_PTR);
/*
* CCU40 - Slice 1 configuration - Timer concatenation
*/
XMC_CCU4_SLICE_CaptureInit(SLICE1_PTR, &capture_timer_concatenation_config);
XMC_CCU4_EnableShadowTransfer(MODULE_PTR, \
(uint32_t)(XMC_CCU4_SHADOW_TRANSFER_SLICE_1| \
XMC_CCU4_SHADOW_TRANSFER_PRESCALER_SLICE_1));
/* Get the CCU4 slice out of idle mode */
XMC_CCU4_EnableClock(MODULE_PTR, SLICE1_NUMBER);
/* Start the CCU4 Timer */
XMC_CCU4_SLICE_StartTimer(SLICE1_PTR)
Also, is there any XMCLib example on this?
Thx
