If the jump table position is across a ROM boundary (0x00FF~0x0100), the “@JMP_A” macro will adjust the jump table
routine begin from next RAM boundary (0x0100).
Example: “@JMP_A” operation.
; Before compiling program.
ROM address
B0MOV
A, BUF0

; “BUF0” is from 0 to 4.
@JMP_A
; The number of the jump table listing is five.
; ACC = 0, jump to A0POINT
; ACC = 1, jump to A1POINT
; ACC = 2, jump to A2POINT
; ACC = 3, jump to A3POINT
; ACC = 4, jump to A4POINT
