内联汇编改写以下内容： int reg = value ? GPIO_GPSET0 : GPIO_GPCLR0; // Pins 0-31 are in register xxx0, 32-63 are in register xxx1. if (pin > 31) { pin -= 32; reg++; } gpio[reg] = 1 << pin;

asm volatile (
    "ldr r0, %[value]\n\t"
    "cmp r0, #0\n\t"
    "it ne\n\t"
    "movne %[reg], %[set]\n\t"
    "moveq %[reg], %[clr]\n\t"
    "ldr r1, %[pin]\n\t"
    "cmp r1, #31\n\t"
    "ble end\n\t"
    "sub r1, r1, #32\n\t"
    "add %[reg], %[reg], #4\n\t"
    "end:\n\t"
    "ldr r2, %[gpio]\n\t"
    "ldr r3, [%[reg]]\n\t"
    "ldr r4, %[pin]\n\t"
    "mov r5, #1\n\t"
    "lsl r5, r4\n\t"
    "orr r3, r5\n\t"
    "str r3, [%[reg]]\n\t"
    :
    [reg] "=r" (reg)
    :
    [value] "m" (value),
    [set] "i" (GPIO_GPSET0),
    [clr] "i" (GPIO_GPCLR0),
    [pin] "m" (pin),
    [gpio] "m" (gpio)
    :
    "r0", "r1", "r2", "r3", "r4", "r5"
);

其中，`value` 为输入值，`GPIO_GPSET0` 和 `GPIO_GPCLR0` 为常量，`pin` 为输入值，`gpio` 为指针。
