ECALL, ECALLP
[Operation performed after subroutine program execution]
*1: Stores the execution result of the subroutine program.
*2: Replaced by the value of the function device.
(7) The numbers of the devices designated by the arguments in the ECALL(P) instruction should not overlap. If they do
overlap, it will not be possible to obtain accurate calculations.
(8) Up to 16 levels of nesting can be used with the ECALL(P) instruction. However, this 16 levels is the total number of
levels in the CALL(P), FCALL(P), ECALL(P), EFCALL(P), and XCALL instructions.
(9) Devices which are turned ON within subroutine programs will be latched even if the subroutine program is not executed.
Devices turned ON during the execution of a subroutine program can be turned OFF by the EFCALL(P) instruction.

(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into
SD0.
