| CALL | Call a subroutine in lower 64 K | |
| Syntax | CALL dst | |
| Operation |
dst → tmp 16-bit dst is evaluated and stored
|
|
| Description | A subroutine call is made from an address in the lower 64 K to a subroutine address in the lower 64 K. All 7 source addressing modes can be used. The call instruction is a word instruction. The return is made with the RET instruction. | |
| Status Bits | Status bits are not affected.
PC.19:16 cleared (address in lower 64 K) |
|
| Mode Bits | OSCOFF, CPUOFF, and GIE are not affected. | |
| Examples | Examples for all addressing modes are given. | |
| Immediate Mode: Call a subroutine at label EXEC (lower 64 K) or call directly to address. | ||
CALL #EXEC ; Start address EXEC
CALL #0AA04h ; Start address 0AA04h
| Symbolic Mode: Call a subroutine at the 16-bit address contained in address EXEC. EXEC is located at the address (PC + X) where X is within PC ± 32 K. | ||
CALL EXEC ; Start address at @EXEC. z16(PC)
| Absolute Mode: Call a subroutine at the 16-bit address contained in absolute address EXEC in the lower 64 K. | ||
CALL &EXEC ; Start address at @EXEC
| Register mode: Call a subroutine at the 16-bit address contained in register R5.15:0. | ||
CALL R5 ; Start address at R5
| Indirect Mode: Call a subroutine at the 16-bit address contained in the word pointed to by register R5 (20-bit address). | ||
CALL @R5 ; Start address at @R5
