Note During saturated operation, the saturated operation results are determined by the contents of the OV
(5) CALLT execution status saving registers (CTPC, CTPSW)
CTPSW
CTPC
There are two CALLT execution status saving registers, CTPC and CTPSW.
When the CALLT instruction is executed, the contents of the program counter (PC) are saved to CTPC, and
the program status word (PSW) contents are saved to CTPSW.
The contents saved to CTPC consist of the address of the next instruction after the CALLT instruction.
The current PSW contents are saved to CTPSW.
Bits 31 to 26 of CTPC and bits 31 to 8 of CTPSW are reserved (fixed to 0) for future function expansion.
flag and S flag. The SAT flag is set (to 1) only when the OV flag is set (to 1) during saturated operation.
