TMS320F280049: "ALIGN(4)" function in F280049 ".cmd" file

Hello Champs,

In C2000ware "28004x_generic_flash_lnk.cmd", there are below definitions:

codestart : > BEGIN, PAGE = 0, ALIGN(4)

.text : >>FLASH_BANK0_SEC1 | FLASH_BANK0_SEC2 | FLASH_BANK0_SEC3, PAGE = 0, ALIGN(4)

.cinit : > FLASH_BANK0_SEC1, PAGE = 0, ALIGN(4)

.pinit : > FLASH_BANK0_SEC1, PAGE = 0, ALIGN(4)

.switch : > FLASH_BANK0_SEC1, PAGE = 0, ALIGN(4)

.reset : > RESET, PAGE = 0, TYPE = DSECT /* not used, */

.cio : > RAMLS0, PAGE = 0

.stack : > RAMM1, PAGE = 1

.ebss : > RAMLS5, PAGE = 1

.esysmem : > RAMLS5, PAGE = 1

.econst : > FLASH_BANK0_SEC4, PAGE = 0, ALIGN(4)

Would you please kindly help what about the function for "ALIGN(4)"? When should it be used?

Thanks!

Best Regards,
