COMPLETE MMR LISTING
Note that the access type column in Table 10 to Table 26 corres-
ponds to the access time reading or writing an MMR. It depends
on the AMBA bus used to access the peripheral. The processor
has two AMBA buses: the AHB (advanced high performance
bus) used for system modules and the APB (advanced peri-
pheral bus) used for lower performance peripherals.
