Помогите переписать код для GCC под IAR Опции

[smk]

Суть такова: помещаем массив во flash и потом побайтно читаем.
В GCC:

Код

unsigned char brightness[256] PROGMEM = //табличка визуально равномерно наращивающая яркость
{0,0,0,1,1,2,2,3,3,4,4,4,5,5,6,6,6,7,7,8,8,8,9,9,10,10,10,11,11,12,12,
12,12,13,13,13,13,13,14,14,14,14,15,15,15,16,16,16,16,17,17,17,18,18,

253,254,255};

if((pwm>pgm_read_byte(&brightness[count_pwm]))|(pwm==0)){sig_off;}

А как такое делается в IAR? Спасибо.

Оптимизация максимальная по размеру.
