Registers
There are two types of multi-purpose registers in the FR family. One is a dedicated purpose register that exists
within the CPU and the other is a multi-purpose register that exists in the memory.
Dedicated Registers
Program Status (PS)
PS is the register that holds the program status and is classified into three categories, namely, Condition Code
Register (CCR) , System Condition Code Register (SCR) and Interruption Level Master Register (ILM) .
Program Counter (PC)
: 32-bit length; indicates instruction storage position.
Program Status (PS)
: 32-bit length; stores register pointers and condition codes.
Table Base Register (TBR)
: Holds the starting address of the vector table to be used for Exception,
Interruption and Trapping (EIT) .
Return Pointer (RP)
: Holds the address to return to from the sub-routine.
System Stuck Pointer (SSP)
: Indicates the system stuck position.
User Stuck Pointer (USP)
: Indicates the user’s stuck position.
Multiplication and Division
Results Resister (MDH/MDL) : 32-bit length; act as registers for multiplication and division.
