Backup Self Refresh - DDR2 managing issue?!

[SimoneBongini]

Hello
file master/driver/ddramc.c line 888
`
#if defined(DEBUG_BKP_SR_INIT)
usart_puts("BKP: pads CX\n");

/* take some time to re-synchronize pads with DDR controller */
mdelay(1000);

#endif
`
Is it correct? Or the delay should be places outside the define?

Thanks
