TMS320F28027: ccs自带的f2802x系列cmd文件内容与datasheet对不上的疑问

以目前使用的TMS320F28027为例，其他型号还没有试过。

CCS Version: 11.0.0.00012

路径：ti\c2000\C2000Ware_4_00_00_00\device_support\f2802x\common\cmd

以下是上述路径下的F28027.cmd文件内容，MEMORY部分原封不动copy过来的

MEMORY
{
PAGE 0:    /* Program Memory */
           /* Memory (RAM/FLASH/OTP) blocks can be moved to PAGE1 for data allocation */

   PRAML0      : origin = 0x008000, length = 0x000800     /* on-chip RAM block L0 */

   FLASHD      : origin = 0x3F0000, length = 0x002000     /* on-chip FLASH */
   FLASHC      : origin = 0x3F2000, length = 0x002000     /* on-chip FLASH */
   FLASHA      : origin = 0x3F6000, length = 0x001F80     /* on-chip FLASH */
   CSM_RSVD    : origin = 0x3F7F80, length = 0x000076     /* Part of FLASHA.  Program with all 0x0000 when CSM is in use. */
   BEGIN       : origin = 0x3F7FF6, length = 0x000002     /* Part of FLASHA.  Used for "boot to Flash" bootloader mode. */

   IQTABLES    : origin = 0x3FE000, length = 0x000B50     /* IQ Math Tables in Boot ROM */
   IQTABLES2   : origin = 0x3FEB50, length = 0x00008C     /* IQ Math Tables in Boot ROM */
   IQTABLES3   : origin = 0x3FEBDC, length = 0x0000AA      /* IQ Math Tables in Boot ROM */

   ROM         : origin = 0x3FF27C, length = 0x000D44     /* Boot ROM */
   RESET       : origin = 0x3FFFC0, length = 0x000002     /* part of boot ROM  */
   VECTORS     : origin = 0x3FFFC2, length = 0x00003E     /* part of boot ROM  */

PAGE 1 :   /* Data Memory */
           /* Memory (RAM/FLASH/OTP) blocks can be moved to PAGE0 for program allocation */
           /* Registers remain on PAGE1                                                  */

   BOOT_RSVD   : origin = 0x000000, length = 0x000050     /* Part of M0, BOOT rom will use this for stack */
   RAMM0       : origin = 0x000050, length = 0x0003B0     /* on-chip RAM block M0 */
   RAMM1       : origin = 0x000400, length = 0x000400     /* on-chip RAM block M1 */
   DRAML0      : origin = 0x008800, length = 0x000800     /* on-chip RAM block L0 */
   FLASHB      : origin = 0x3F4000, length = 0x002000     /* on-chip FLASH */
}

上面两个图是2802x的datasheet截图，datasheet中只有28027-Q1，没有单独28027，姑且认为28027和28027-Q1一样的。

第一个问题：cmd文件中PAGE 1里面的BOOT_RSVD起始地址是0x000000，length是0x000050，RAMM0起始地址是0x000050，length是0x0003B0。这两段我理解的是与datasheet中的M0 Vector RAM和M0 SARAM对应，但是datasheet中M0 SARAM的起始地址是0x000040，不是0x000050，length 0x0003B0是对的。

第二个问题：PAGE 0里面的VECTORS     : origin = 0x3FFFC2, length = 0x00003E，但是datasheet中的起始地址是0x3FFFC0。
