8.8.3
PCR subsystem clock description
The PCRSS is clocked by a number of different clocks. CLK_SYS_PCRSS clocks the
AHB side of the AHB to DTL bus bridge and CLK_PCR_SLOW clocks the CGU, RGU and
PMU internal logic, see
Section 7.2.2
. CLK_SYS_PCRSS is derived from
BASE_SYS_CLK, which can be switched off in low-power modes. CLK_PCR_SLOW is
derived from BASE_PCR_CLK and is always on in order to be able to wake up from
low-power modes.
