How to avoid the warning 1352 in xc8 compiler?

Question

I used this macro in the xc8 compiler from microchip:

#define Unlock()  \
          do { \
              asm("BANKSEL PPSLOCK");   \
              asm("MOVLB   PPSLOCK");   \
              asm("MOVLW   0x55");      \
              asm("MOVWF   PPSLOCK");   \
              asm("MOVLW   0xAA");      \
              asm("MOVWF   PPSLOCK");   \
              asm("BCF     PPSLOCK,0"); \
          } while (0)

This is a special sequence mentioned in the datasheet to unlock the peripherial pin selection.
And always get these warnings:

../_main.c:437: warning: (1352) truncation of operand value (0xea0) to 8 bits
../_main.c:437: warning: (1352) truncation of operand value (0xea0) to 8 bits
../_main.c:440: warning: (1352) truncation of operand value (0xea0) to 4 bits

0xEA0 is the adress of the PPSLOCK register, but I didn't see anything to truncate I just write 8 Bit values in an 8 Bit SFR.

Answer 1

The MOVWF operation takes just 7 bits of the address operand, and you give it 12 bits. That's why you have to select the bank beforehand.
