I have been trying to understand the PSX2 library. I like to understand whats under the hood actually.
here is the code snippet where i am stuck:
inline void PS2X::CMD_SET(void) {
register uint8_t old_sreg = SREG;
cli();
*_cmd_oreg |= _cmd_mask;
SREG = old_sreg;
}
I cant understand *_cmd_oreg |= _cmd_mask; because “_cmd_oreg” is of type uint8_t, why are we using * in front of it. i tried to use it with some other values and different variable name seperately on compiler but it throws up an error “invalid type argument of ‘unary *’ “
