COMPLETE MMR LISTING
Note that the Access Type column corresponds to the access
time reading or writing an MMR, where R is read, W is write,
and R/W is read/write. It depends on the AMBA bus that is
used to access the peripheral. The processor has two AMBA
buses: the advanced high performance bus (AHB ) used for
system modules and the advanced peripheral bus (APB) used
for lower performance peripherals.
