I can not find set INDIRECT MODE function

setMR(mr | MR_IND); This is just a macro. It’s defined:
#define setMR(mr) (((uint8_t)MR) = (uint8_t)((mr) >> 8));(((uint8_t)WIZCHIP_OFFSET_INC(MR,1)) = (uint8_t)((mr) & 0xFF)).
I have not found a function for writing the value 0x1 at address 0x1(MR1) anywhere.
Same problem with reset setMR(MR_RST);
I have not found a function for writing the value 0x80 at address 0x1(MR1) anywhere.
Or did I miss something?
Thank you.
