The Flash Memory Controller (FMC) interfaces to the embedded flash memory for two
tasks:
Base clock
BASE_MSCSS_CLK
BASE_UART_CLK
BASE_SPI_CLK
BASE_TMR_CLK
BASE_ADC_CLK
BASE_CLK_TESTSHELL

•
This clock is always on (cannot be switched off for system safety reasons)
In the peripheral subsystem parts of the Timers, Watchdog Timer, SPI and UART have their own clock
source. See
In the Power Clock and Reset Control subsystem parts of the CGU, RGU PMU have their own clock
source. See
The clock should remain activated when system wake-up on timer or UART is required.
