6.7.2 Base clock and branch clock relationship
Table 7
derived branch clocks. A short description is given of the hardware parts that are clocked
with the individual branch clocks. In relevant cases more detailed information can be
found in the specific subsystem description. Some branch clocks have special protection
since they clock vital system parts of the device and should not be switched off. See
Section 6.15.5
contains an overview of all the base blocks in the LPC2921/2923/2925 and their
BASE_SYS_CLK
CGU0
for more details of how to control the individual branch clocks.
