help !!! lỗi Out Of ROM

[qloi]

mình viết code cho PIC16f59 thì bị lỗi "out of ROM,the segment or program í tô large Main".mặc dù ROM còn rất nhiều(xóa bớt 1 hàm thì còn tới 78% trong khi hàm này tương đương hàm trên) . Mọi người ai biết cách giải quyết chỉ với?

#include <16f59.h>
#device *=8
#fuses xt
#use delay(clock=4000000)
#use fast_io(b)
#use fast_io(c)
