CPU Speed Register [0xC008] [R/W]
Register Description
The CPU Speed register allows the processor to operate at a user selected speed. This register only affects the CPU; all other
peripheral timing is still based on the 48-MHz system clock (unless otherwise noted).
CPU Speed (Bits[3:0])
The CPU Speed field is a divisor that selects the operating speed of the processor as defined in
Table 18.CPU Speed Definition
Reserved
All reserved bits must be written as ‘0’.
