3.2 CPU Register Set
The CPU registers of the V850E/PH2 can be classified into three categories: a general-purpose pro-
gram register set, a dedicated system register set and a dedicated floating point arithmetic register set.
All the registers have 32-bit width.
In addition, the V850E/PH2 contains special system control registers that should be initialized before
CPU operation, and a specific register controlling its clock.
For detailed description of V850E1 core, refer to V850E1 Core Architecture Manual and the
addendum for floating point arithmetic.
