为什么Zone7要分割为PAGE0的ZONE7A和PAGE1的ZONE7B？对访问片外设备有什么影响？
F28335.cmd部分内容：
MEMORY
{
PAGE 0: /* Program Memory */
/* Memory (RAM/FLASH/OTP) blocks can be moved to PAGE1 for data allocation */
……
ZONE7A : origin = 0x0200000, length = 0x00FC00 /* XINTF zone 7 – program space */ ……
PAGE 1 : /* Data Memory */
/* Memory (RAM/FLASH/OTP) blocks can be moved to PAGE0 for program allocation */
/* Registers remain on PAGE1 */
……
ZONE7B : origin = 0x20FC00, length = 0x000400 /* XINTF zone 7 – data space */
……
}

这个注释应该已经告诉你答案了呀：这是用于保存程序数据，而下一段是数据空间。
……ZONE7A : origin = 0x0200000, length = 0x00FC00 /* XINTF zone 7 – program space */ ……PAGE 1 : /* Data Memory *//* Memory (RAM/FLASH/OTP) blocks can be moved to PAGE0 for program allocation *//* Registers remain on PAGE1 */……ZONE7B : origin = 0x20FC00, length = 0x000400 /* XINTF zone 7 – data space */……}
