(5) CALLT execution status saving registers (CTPC and CTPSW)
Note The result of the operation that has performed saturation processing is determined by the contents of the
Maximum positive value is exceeded.
Maximum negative value is exceeded.
Positive (maximum value is not exceeded)
Negative (maximum value is not exceeded)
CTPSW
CTPC
CTPC and CTPSW are CALLT execution status saving registers.
When the CALLT instruction is executed, the contents of the program counter (PC) are saved to CTPC, and
those of the program status word (PSW) are saved to CTPSW.
The contents saved to CTPC are the address of the instruction next to CALLT.
The current contents of the PSW are saved to CTPSW.
Bits 31 to 26 of CTPC and bits 31 to 8 of CTPSW are reserved for future function expansion (fixed to 0).
OV and S flags. The SAT flag is set to 1 only when the OV flag is set to 1 when a saturation operation is
performed.
