tms320F28377D 的emif1_32bit_sdram例程相关问题？

1  __addr32_write_uint16等是编译器内部函数，而不是函数。

The following new intrinsics are available to read from and write to memory using 32-bit addresses. These are for special data placed higher than the usual 22-bit address range.

(unsigned short) __addr32_read_uint16(unsigned long addr);
(unsigned long) __addr32_read_uint32(unsigned long addr);
(void) __addr32_write_uint16(unsigned long addr, unsigned short val);
(void) __addr32_write_uint32(unsigned long addr, unsigned long val);
