Writing 32 bit values to 16 bit register

I have to write 16 bit value in a 16 bit register, & variable which holds that value is 32 bit. I have STM32, BSRRL register which is 16 bit, so if I write Like uint32_t x = 255; BSRRL = x; ...

C51: 32 bits unsigned returned values treated as signed 16 bits

Hi! In a full project a simple unsigned long ( u32 )returned value from a function lead to this (odd) assembler code. It make us think that the u32 is considered as s16 ( signed short ). If...
