I/O Lines
In order to use the I/O lines of this peripheral, the I/O pins must be configured using the I/O Pin Controller (PORT).
- PORT - I/O Pin Controller
Clocks
The TCC bus clocks (CLK_TCCx_APB) where x is 0,1,2...7 is enabled by default, and can be enabled or disabled in the Main Clock (MCLK).
A generic clock (GCLK_TCCx) is required to clock the TCC. This clock must be configured and enabled in the Generic Clock Controller (GCLK) before using the TCC.
The generic clocks (GCLK_TCCx) are asynchronous to the bus clock (CLK_TCCx_APB). Due to this asynchronicity, writing certain registers will require synchronization between the clock domains. Refer to Synchronization for further details.
DMA
The DMA request lines are connected to the DMA Controller (DMAC). In order to use DMA requests with this peripheral the DMAC must be configured first. Refer to the DMAC – Direct Memory Access Controller chapter for details.
- DMAC
Interrupts
The interrupt request line is connected to the Interrupt Controller. In order to use interrupt requests of this peripheral, the Interrupt Controller (NVIC) must be configured first. Refer to the Nested Vector Interrupt Controller chapter for details.
- Nested Vector Interrupt Controller
Events
The events of this peripheral are connected to the Event System.
- EVSYS
Debug Operation
When the CPU is halted in Debug mode, this peripheral will halt normal operation. This peripheral can be forced to continue operation during debugging - refer to the Debug Control (DBGCTRL) register for details.
- TCC DBGCTRL Register
Register Access Protection
Registers with write access can be optionally write-protected by the Peripheral Access Controller (PAC), except for the following registers:
- The Interrupt Flag register (INTFLAG)
- The Status register (STATUS)
- The Period and Period Buffer registers (PER, PERBUF)
- The Compare/Capture and Compare/Capture Buffer registers (CCy, CCBUFy)
- The Control Waveform register (WAVE)
- The Pattern Generation Value and Pattern Generation Value Buffer registers (PATT, PATTBUF)
When the CPU is halted in Debug mode, write-protection is automatically disabled.
Write protection does not apply for accesses through an external debugger.
