2.2.3
System registers consist of four 32-bit registers: high and low multiply and accumulate registers
(MACH and MACL), the procedure register (PR), and the program counter (PC).
Multiply-and-Accumulate Registers (MAC): Registers to store the results of multiply-and-
accumulate operations.
Procedure Register (PR): Registers to store the return address from a subroutine procedure.
Program Counter (PC): Registers to indicate the sum of current instruction addresses and four,
that is, the address of the second instruction after the current instruction.
