This section describes the GTC integration in the device, including information about clocks, resets, and hardware requests.
Figure 12-2407 shows the GTC integration.
Figure 12-2407 GTC IntegrationTable 12-4582 through Table 12-4585 summarize the GTC integration.
| Module Instance | Power Sleep Controller | Power Domain | Module Domain | Interconnect |
|---|---|---|---|---|
| GTC0 | PSC0 | PD0 | LPSC0 | CBASS0 |
| Module Instance | Module Clock Input | Source Clock Signal | Source | Description |
|---|---|---|---|---|
| GTC0 | GTC_CLK | MAIN_PLL2_HSDIV5_CLKOUT(1) | PLL2 | Module functional (counter) clock. Source clock selection is done through a mux which is controlled via CTRLMMR_GTC_CLKSEL[2-0] CLK_SEL register bit field. |
