TMS320F2800157: flash power down before enter halt mode

Part Number: TMS320F2800157

Dear Champs,

I am asking this for our customer.

in the F280039 example code (lpm_ex5_haltwake_gpio), customer found there are "Flash_powerDown(FLASH0CTRL_BASE);" before enter halt mode.

it seems this function will power down the flash bank to saving power in the halt mode.

 but in the F2800157 example code (lpm_ex5_haltwake_gpio), it seems there are no "Flash_powerDown" before enter halt mode.

So customer question is whether it means the flash of F2800157 is no need to power down manually before enter halt mode? will it power down automatically?

or the F2800157 flash could not be power down? 

Regards,

Daniel
