RP (Return Pointer)
The return pointer contains the address to which to return from a subroutine.
When the CALL instruction is executed, the value in the PC is transferred to the RP.
When the RET instruction is executed, the value in the RP is transferred to the PC.
The initial value after a reset is indeterminate.
SSP (System Stack Pointer)
The SSP is the system stack pointer and functions as R15 when the S flag is “0”.
The SSP can be explicitly specified.
The SSP is also used as the stack pointer that specifies the stack for saving the PS and PC when an EIT event
occurs.
The initial value after a reset is 00000000H.
USP (User Stack Pointer)
The USP is the user stack pointer and functions as R15 when the S flag is “1”.
The USP can be explicitly specified.
The initial value after a reset is indeterminate.
This pointer cannot be used by the RETI instruction.
MDH, MDL (Multiply and Divide register)
These registers hold the results of a multiplication or division. Each of them is 32-bit long.
The initial value after a reset is indeterminate.
