PUSHX.A | 将单地址字保存至堆栈 | ||
PUSHX.[W] | 将单字写入堆栈 | ||
PUSHX.B | 将单字节写入堆栈 | ||
语法 | PUSHX.A src | ||
PUSHX src 或 PUSHX.W src | |||
PUSHX.B src | |||
操作 | 将源操作数的 8/16/20 位值保存在 TOS 中。可使用 20 位地址。写入操作前,SP 减 2(字节和字操作数)和减 4(地址字操作数)。 | ||
说明 | SP 减 2(字节和字操作数)或减 4(地址字操作数)。然后源操作数被写入 TOS。对于源操作数,所有七个寻址模式均可使用。 | ||
状态位 | 状态位不受影响。 | ||
模式位 | OSCOFF,CPUOFF 和 GIE 不受影响。 | ||
示例 | 将字节保存在堆栈上的 20 位地址 &EDE 内。 |
PUSHX.B &EDE ; Save byte at address EDE
示例 | 将 20 位值保存在堆栈上的 R9 中。 |
PUSHX.A R9 ; Save address-word in R9
