子例程
CALL dst
dst → tmp 评估并存储 dst
SP-2→SP
PC → @SP 将 PC 更新至 TOS
tmp → PC 将 dst 保存至 PC
在 64K 地址空间内的任一地址上进行子例程调用。所有寻址模式都可以使用。返回地址(下一条指令的地址)存储在堆栈中。调用指令是一个字指令。
状态位不受影响。
给出了所有寻址模式的示例。
CALL #EXEC ; Call on label EXEC or immediate address (e.g. #0A4h)
; SP-2 -> SP, PC+2 -> @SP, @PC+ -> PC
CALL EXEC ; Call on the address contained in EXEC
; SP-2 -> SP, PC+2 ->SP, X(PC) -> PC
; Indirect address
CALL &EXEC ; Call on the address contained in absolute address
; EXEC
; SP-2 -> SP, PC+2 -> @SP, X(0) -> PC
; Indirect address
CALL R5 ; Call on the address contained in R5
; SP-2 -> SP, PC+2 -> @SP, R5 -> PC
; Indirect R5
CALL @R5 ; Call on the address contained in the word
; pointed to by R5
; SP-2 -> SP, PC+2 -> @SP, @R5 -> PC
; Indirect, indirect R5
CALL @R5+ ; Call on the address contained in the word
; pointed to by R5 and increment pointer in R5.
; The next time S/W flow uses R5 pointer
; it can alter the program execution due to
; access to next address in a table pointed to by R5
; SP-2 -> SP, PC+2 -> @SP, @R5 -> PC
; Indirect, indirect R5 with autoincrement
CALL X(R5) ; Call on the address contained in the address pointed
; to by R5 + X (e.g. table with address starting at X)
; X can be an address or a label
; SP-2 -> SP, PC+2 -> @SP, X(R5) -> PC
; Indirect, indirect R5 + X
