[ Function ]
*1
n denotes the number of instruction bytes.
• This instruction causes control to jump to a subroutine at the address indicated by
src
. If
src
is
memory, specify the address at which the low-order address is stored.
• If you selected (.W) for the jump distance specifier (.length), control jumps to a subroutine at the start
address of the instruction plus the address indicated by
src
(added including the sign bits). If
src
is
memory, the required memory capacity is 2 bytes.
• If
src
is memory when you selected (.A) for the jump distance specifier (.length), the required memory
capacity is 3 bytes.
[ Operation ]

When jump distance specifier (.length) is (.A)
