Registers
The FR series has two types of registers: application-specific registers in the CPU and general purpose registers
in memory.
Dedicated registers
PC (Program Counter)
The PC is the program counter and stores the address of the currently executing instruction.
Table base register (TBR)
The TBR is the table base register and stores the top address of the vector table used by the EIT function.
Program counter (PC)
: 32-bit register. Stores the current instruction address.
Program status (PS)
: 32-bit register. Contains the register pointer and condition code.
Table base register (TBR)
: Stores the top address of the vector table used by the EIT (exception/interrupt/
trap) function.
Return pointer (RP)
: Stores the subroutine return address.
System stack pointer (SSP)
: Points to the system stack area.
User stack pointer (USP)
: Points to the user stack area.
Multiplication and division
result register (MDH/MDL)
: 32-bit registers used for multiplication and division.
