CPU Speed Register [0xC008] [R/W]
Table 26. CPU Speed Register
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 27. CPU Speed Definition
Reserved
Write all reserved bits with ’0’.
