Bit Field Type Reset Description
31-24 RESERVED R X
Software should not rely on the value of a reserved. Writing any
other value than the reset value may result in undefined behavior.
23-0 FRO_MASK R/W X
De-tune bits for the individual FROs. A '1' in bit [n] lets FRO 'n ' run
approximately 5% faster. The value of one of these bits may only be
changed while the corresponding FRO is turned off (by temporarily
writing a '0' in the corresponding bit of the FROEN.FRO_MASK
register).
