and seven power domains except System Timer, ALIVE and RTC can be power-off by turning off switch cells
which connects the current path from VDD to GND.
How to control the power mode of Cortex-A8, SRAM, and other hard macros included in each power domain is
summarized in Table 2.4-8 and the detail description is given in Section 6 HARD MACRO POWER CONTROL.
Each hard macro has its own power-down mode. The power mode of SRAM, ROM, PLL, TS ADC and I/O are
controlled by power management. The power mode of hard macros except SRAM, ROM, PLL, TS ADC and I/O
should be controlled by corresponding control module. Note that in addition to PMU, CLKCON also controls the
PLL.
