3.5.3.4.1.3 SGX Power Domain
This section describes all modules and features in the high-tier device. To save power, ensure that power
domains of unavailable features and modules are switched off and clocks are cut off.
The SGX subsystem interface clock is sourced by the L3 clock. The functional clock source can be
selected between CORE_CLK, COREX2_CLK, CM_96M_FCLK and SGX_192M_FCLK. When the
functional clock source is CORE_CLK, its frequency can be divided (by 2, 3, 4, or 6). When the functional
clock source is COREX2_CLK, its frequency can be divided (by 3 or 5).
shows the clocking scheme in the SGX power domain.
