Change DSPS scatter file

Dear Dialog,

I want to change the scatter file of DSPS project (DSPS_v_5.150.2) because the code size is not enough.
So, I just changed ER_IROM5 size, is it OK ?

1. Before
---------------------------------------------------------------------------------------------------------------------------------------------------------
LR_IROM5 0x20000440 0x93c0 {
ER_IROM5 0x20000440 0x7ac0 {
*(InRoot$$Sections) ; All library sections that must be in a
; root region, for example, __main.o,
; __scatter*.o, __dc*.o, and * Region$$Table
boot_vectors.o (+RO)
system_ARMCM0.o (+RO)
;*armlib* (+RO)
.ANY (+RO)
.ANY (+RW)
}
---------------------------------------------------------------------------------------------------------------------------------------------------------
2. After
---------------------------------------------------------------------------------------------------------------------------------------------------------
LR_IROM5 0x20000440 0x93c0 {
ER_IROM5 0x20000440 0x7bc0 {
*(InRoot$$Sections) ; All library sections that must be in a
; root region, for example, __main.o,
; __scatter*.o, __dc*.o, and * Region$$Table
boot_vectors.o (+RO)
system_ARMCM0.o (+RO)
;*armlib* (+RO)
.ANY (+RO)
.ANY (+RW)
}
